I could see you making a few prototypes and then having those mass-produced and sold like board games. I think it would do really well in art supply and school supply (for teachers) stores!
I crossposted your post in the Alien Art Hive community and reblogged it too. I hope all of our artists here on Hive check it out! I really think it was/is a super cool idea!
I also visualize that.. hope I can make it happen. I´d love to see them being used in schools!
