I always keep a pad of blank typing paper or art paper at my side to serve as canvas for impromptu 'lectures' on subjects.

Sometimes it comes out looking like an art piece, and so has developed into a plan to create paintings with pieces of info drawn out as objects describing the subject.

Also Meme Murals to paint onto walls to replace unicorn graffitti as social comment. leaving the viewer to attempt to 'find the open secret' in it.
