Repurpse a dry erase poster?

[muggleangel.livejournal.com]

So I've got this cool dry erase poster for my wall, but sadly the adhesive on the back is no longer sticky enough to keep it on my wall. It's a flexible plastic, and I'm just convinced that there is something cool and crafty I can do with it, but I am at a loss as to what.

If I can't think of anything I'm just going to cut it up and dry-cement it to pieces of cardboard to make doodle boards, but do any of you crafty people have clever ideas to reuse this cool material?
