Any Idea for 100th October Revolution Anniversary?

Anything "Ultra-Epic" or edgy, without spending any funds (exclude DIY stuff), and legal (i am arent sure did i can hang S.Union flag in my balcony, 'cause i am life in Poland ) also nothing that glorify, sharing hatred itc. about Communism, something neutral but with lil'smile. (Also this stuff that can be something "Internet/Computer Related" a.k.a... Nevermind, i cant make example but you get an idea).
