Someone just showed me something that I've not seen and don't have an
explanation for. You know those cards that you rub off with a coin that you
get at fast food places that tell you youv'e won a coke or something? I saw
one today that is heat sensitive, you hold it or blow on it and it becomes
transperant for a while, revealing writting underneath. I suppose it is
similar to those liquid crystal thermal sheets that show your hand print
when you put your hand on them. The person who showed it to me was an
artist and wanted to know if there was a source for the material or a way
to make it. Does anyone have a resource for this they can point me too?
