Artist Melissa Gay

Artist Melissa Gay

I am a neurodiverse LGBTQ+ artist who is equally passionate about sci-fi, fantasy, and wildlife art. I use traditional media such as pencils, acrylics, watercolors, and oil paints. Myths and legends about the natural world inspire me, as does our increasingly detailed view of the Universe through science and technology. From this I can conclude that I love detail!!! But I also love mystery!!! My greatest joy is creating hazy, dreamlike, otherworldly scenes with just enough detail to fire the viewer's imagination and inspire them to fill in the story. I think of it as creating personal myths, and like all good myths, they grow and thrive with what the minds of new observers add to the tales.

For over twenty years I have been an award-winning cover artist and illustrator for publishers such as Baen Books, Llewellyn Worldwide, Hay House, 78 Tarot, and many tabletop RPG companies. Among the ENnie-award-winning and fan favorite games I have helped to illustrate are the Dresden Files RPG, Fate Core, Part-Time Gods, Mermaid Adventures, Hero System, Trail of Cthulhu, 13th Age, The Dracula Dossier, and Surviving Strangehollow. My imaginative realist work has been featured in ImagineFX Magazine, io9, tor.com, and several IBA anthologies, and I have won two Chesley awards. I have two art books, Finding My Familiar (wildlife drawings) and Earth and Water (ink paintings), and I am working on a book of acrylic space paintings called I Dream of Space. I'm a proud member of the Changeling Artist Collective and of ASFA, and I co-founded of the Birdwhisperer Project.

Apart from drawing and painting, I am never happier than when gaming with my spouse, or in the woods hunting for secret waterfalls and climbing on rocks!

Toastmaster Tadao Tomomatsu

Parts Made in Japan-Assembly in the USA

A WORK OF SCIENCE FICTION/Fantasy/Etc.?

Long ago, no no not that far away. An Origin Story?

Tadao was manufactured with parts from Japan and Assembly in the U.S.A.. the confusing part was the Apple OS in a PC system.. or was that the other way around?

Not so typically: Father- Renaissance Scientist of the ages

               Mother- Professor of Japanese/Culture/Professional Translator.

And that all blew up when the family in Japan took pity and sent Japanese toys before they became worldwide wonders.

Fascinated by Giant robots, Science Ninja's super equipment fighting the aliens.

And growing up a bit of a TV head: Watching PBS, Dr. Who, Danny Kaye and John Wayne didn't help.   May have confused people more in schools when the southern accent would pop out.  Or British... followed by Scottish... (don't ask).

And theater was a downfall... or was it being a Radio DJ in Chicago that no one knew about?  “A great face for radio..”

Then California bound: Actor, Singer, dancer(sometimes) Stunts-various. Entertainer, MC, Impersonator, Props, sets, even a period of Director, Writer, Producer even a Comedian with weekly times at the Laugh Factory and the Comedy store back in the day.

With some of the strangest stories- ask sometime about:

How he was not Japanese enough for the movie Pearl Harbor. ONE of MANY… le sigh.

Some of the highlights in Hollyweird:

Mr.Shake-Hands Man – USA/2: For the British/American TV Show “BANZAI”. A game show of various segments.  Mr. Shake-Hands Man would shake hands with celebs on the Red Carpet and how long would he shake hands.  You had to guess.

Maybe even a Baby Septuplet on the Tonight Show.

A bewildered tourist in Inspector Gadget.

NYPD Translator in “HEROES” and yes oddly with the Speaking roles. Makes him BOTH a DC And Marvel Character and you can find his profile in the HEROES graphic novel.

And the least recognized. Was on CyberRadioTV.com.  The world's first 24hr. Internet “Radio” station.  Groundbreaking and innovation provided and IDEAS from Tadao. Which was kind of a base for all other internet shows to eventually things like YouTube and other online productions.

Alas Not much credit.

On the Fannish side was a Con-Chair for Loscon in LA.  Even relaxacons for LASFS.  MC, Toastmaster, Auctioneer. Host or even Booth babe (it's for Worldcon in Anaheim in 2026).

Working at Gallifrey One (yarp Dr.Who). and a “Guardian of the TARDIS”.  They were never clear Tho if it was the White or Black Guardian. Wait? Wrong show?? Um..

Or even working Labyrinth of Jarreth Masquerade (LOJ). Either, onstage with the vaudeville stylings of the Goblins. To Small Crafty service for the rest of the actors er I mean Elves, Sypher Royals, Mermaids, Elementals or even a Dragon or three.. or am I patching up the Knights? The Attendees??  Er never mind.

Mostly retired from Acting.

He has taken over his father's works.  As Dr. Hideo Tomomatsu and Prof. Yuko Tomomatsu had many scientific works since their passings.

So now very Science Adjacent.

Happily finds LosCon to be one of his Home Conventions and happy to have some chosen family time.

And Thanks everyone for their time, efforts, support for putting up with me or at least keeping science fiction and fantasy alive and well.. 😊

DemiCon Hall of Fame

At DemiCon 15 we wanted a way to extend special acknowledgement those who have helped make DemiCon what is today. The DemiCon Hall of Fame was created to recognize those particularly influential individuals.

Rusty “James” Hevelin

At DemiCon 15, Rusty Hevelin was our first inductee to DemiCon Hall of Fame. Rusty had started as our Fan Guest of Honor at DC 1, but somewhere before our first convention came around, he was named Toastmaster. From that day forth, he was our Toastmaster. When Rusty became a member of the DemiCon Hall of Fame, he was given the title of Toastmaster Emeritus, but he did not rest on his laurels and has been at every DemiCon until DC22 when health problems kept him away. Rusty passed away in 2011.

To learn more about Rusty, follow this link to the Hevelin Collection at the University of Iowa.

Joe and Gay Haldeman

Gay and Joe had an intricate part in growing the love of science fiction in those who created DemiCon when they were members of Science Fiction League of Iowa Students (which Joe created) and running ICON. Gay and Joe have been dubbed by those that were under their tutelage as the “Grandparents” of DemiCon.

Joe Haldeman is a multiple Hugo and Nebula award winning author. For his spectacular career in writing science fiction and fantasy, he was given the honor of SFWA Grand Master. Joe has been our Author GOH for DC 2 and DC 20 where the Haldemans were inducted into the DemiCon Hall of Fame.

Gay Haldeman was our Fan Guest of Honor at DC 2 and was a regular guest, besides Rusty Hevelins' travel buddy through the many years. Mary Gay Potter Haldeman (a name familiar to those who read The Forever War) has a Master's Degree in Spanish Literature and another in Linguistics. Joe and Gay are retired in Florida after many years of teaching at MIT . But, Joe is not the only one with an award or two. Gay shared a Skylark Award with Joe in 1996, and in 2011 was given the Big Heart Award at the World SF Convention in Reno, Nevada. Both Gay and Joe have thespian talents and have graced our stage as TICC performers, as well.

Glen Cook

Glen was made a member at DemiCon 25. Glen Cook Author guest of honor for DemiCon 5, known for his stellar The Black Company military fantasy series and so much more, told DemiCon this: I was born and am still under foot. Hit the ground in NYC in 1944, lived there, Indiana, and California growing up. Served in the Navy, attended U of Missouri, worked for General Motors and retired therefrom. Began writing with intent to commit publication late 1960s and have since produced more than 50 published books, some short fiction, some articles and some essays. I have three sons, an Army officer, an architect, and a symphony musician, plus numerous grandchildren, all but one of whom seem determined to be female. And I have an amazing wife who has been with me for almost 45 years. These days I am, extremely slowly, working on expanding the Black Company chronicles by two novels and a story collection. I have become a victim of Ambition Deficit Disorder, which is what has put the slow in slowly.

Glen attended many DemiCons, selling books to all who love the joy of reading. Signing his and making DemiCon even more special. While Glen has "retired" from our Dealer Room he made a lasting impact. Thanks Glen.

Glen Cook

Carol Eis and Karen Eis

Carol and Karen Eis are the unsung heroes of the Art Show. Lovingly known to all as the Eis Sisters, these two showed up on a DemiCon of many years past to volunteer and stayed. Coming in to help behind the scenes for both show and auction, they make sure all runs smoothly. The Eis Sisters have even helped train some of our art show department heads on the little tricks of the trade. DemiCon is fortunate to have Carol and Karen as volunteers throughout the years.
