SudoKit
Learning... not just for kids but also adults, old people, and even small animals!
Small animals, kids, and adults start out holding a pretty box full of SudoKit stuff. It holds learning placemats, shadowbox tool placemats, and small useful charms like an hourglass to measure time spent offline while learning stuff (internet addiction is a big problem). And in the process the community at SudoRoom can print, build and make the kits too! all open source!
