I'm trying to remember the name of a sort of craft set/toy thing I used to get when I was wee. Basically you got a metal frame, and some wee plastic beads. You poured the plastic beads into the metal frame then put it in the oven, the plastic melted and created a stained glass effect.
The end results look like this:

The reindeer and I think the "season's greetings" things are, I'm pretty sure, made of the same stuff, we've got that same reindeer and I made it.
