We went through many whiteboard-, conversation-, pagefuls of ideas, some reasonable, most not. 57aMP was our one success. (We had many, many other failures. RIP, photobomb; and another success, 57fire)
What if you could create physical stamps using the heat?
In 57aMP, we made a thermal touch pad, which turn from black to white when heated. We digitalized the thermal input into a 2D stamp using a mobile camera. While powering the pad with heat, the user could watch the real-time visualization via web. Finally, 3D stamp models were generated from the thermal input and we use 3D printer to make physical stamps from the heat.
black thermochromic pigment
transparent acrylic base
clear 11" x 14" acrylic sheets
painting supplies: paint brush, paper towels, plastic containers, etc.
mix paint (with care, you're turning pigment into paint)
paint acrylic, one layer at a time
interact with the paint: hands, tea, whatever
have iPhone/iPad watch the surface (passive, periodic pictures)
discretize images into a black/white grid (which can be represented as a binary string)
convert said strings into 3d stamps (via custom
print 3d stamps
play with stamps: apply ink and print, heat up and heat-stamp the painted acrylic, the sky's the limit
Repeat (3) - (8) as much as you like. Repeat (1) - (2) as needed. Optionally watch the web interface to see what the camera is seeing.
The paint's actually a bit finicky. (Turning pigment into paint was an experience.) But mostly, we're just sad it doesn't turn
-- it turns
Body heat does work, but it takes a few seconds (longer if your hands are cold). Hot water works best for immediate black-white color change, but takes a while (ten minutes or so) to fade back to black. (Maybe that's why these people wiped down this

The interactive fire in the holographical display is controlled based on the the percentage of white dots from the thermal input.
The user could also play with the fire by touching the camera on the iPhone. It turns your camera into a button to control the illusion!
