So, we've done one page, 24 hour, ingredients based, here's another way to make a game: on a poster. The wonderful John Ross has popped Risus on a single poster:

I appreciate that the poster isn't free but what a cool idea. I wonder what other firm factors are possible? System on a mug? On a T-shirt?
Another idea that's popped in us "pass the parcel". Back in my winner days, I used to do a lot of Photoshop. We would do " collabs" where someone started and you passed the PSD from person to person, adding images etc as you went. Would anyone be up for this?
