The collection on display at the Ransom Center is truly impressive. With a variety of interpretations and publications of the Alice book, as well as other materials owned by Carroll. We are happy to say that we helped develop the activities area devoted to mathematical activities, games and puzzles. That area includes giant Tangrams made by the laser wizards at MakeATX, large scale 64=65 puzzles made by us, a scale measurement activity, and origami.
