Suggested contest: BUCKETS!
I believe I saw it suggested elsewhere, and forgive me if it already happened and I managed to miss it entirely, but: how about a "bucket" contest? There are so many projects out there already and countless more still locked up in our collective brains, it would be nice to see all of that gray matter on display. In buckets.
This has taken over my own brain recently because I'm knee-deep in a couple of buckularish projects right now (and will of course be instructable-ising them regardless), but there's nothing like a contest to kick everybody's creativity up a notch. The 5-gallon bucket in particular is such a ubiquitous and versatile creature, free or cheap, available in food-safe or full of toxic chemicals... how about a community-wide renewal of our devotion to the noble bucket!
