The next gamejam will mark a year of gamejams here on gd.se! Consequently, we should make sure it's a special kind of gamejam with... special kind of stuff in it.

You get the point. We need some sort of ideas. We're not time pressed though, so feel free to think for as long as you want. Whenever you can think of something appropriate, post it as an answer here. The jam will most likely take place on the 23rd (or rather 24th) of October, for a proper anniversary, though this is not exactly settled yet.

I'll bake a cake.
