Since the website provide no search capability, and even the "all tags" list never seems to be updated, we'll have to organize things ourselves, by creating themed galleries.
I have created two such galleries for general use:
Best of Scratch (this is intended for programs that show off good programming
tricks, but good animations and games are welcome, as long as they
are not badly programmed)
Names Gallery (this is intended for name animations. I saw there there were
several out there, but there was no way to find them again.)
I seeded the galleries with some of my own stuff, but the intent is not for them to showcase *my* work, but to collect stuff on a theme.
There is already a Math Connections gallery that mathy stuff should be submitted to (though I saw some interactive art there that seemed not to belong).
