Just tried this in the office with my phone. Impressive! You should submit this as a Show HN - really deserves to get some reviews.

Good fun for those with kids and even mucking around in the office demoing to friends.

You should throw some more money at this to get a few dozen more models/pages going. I can't think of a 1-5 yo that wouldn't like this. Colleague with children said "My kids are going to lose their shit when they see this."
