For the stretch goals, the creators are asking for backers to post:

(1) art that would have been better without imperial/colonialist themes
(2) favorite anti-colonialist art
(3) favorite revolutionary songs

I have tons of revolutionary songs, but I don't know much art! If anyone has any ideas they don't mind me reposting for credit on the Kickstarter campaign (just unlocking stretch goals, I think), I'd appreciate it!
