The art work is so incredibly creative in Planck's Room. Each room and each inventor has been so much fun to explore and to learn more about. I enjoyed the history and learning about these incredible, brilliant, inventive people. It was especially exciting searching for all the brains in Charles Babbage's room and the quibit gremlins throughout each room. By the way, this was the first I have ever heard about this brilliant "father of computers" who lived in the 1800's. It's a very fun and inspiring game to play with children or adults, or even in a classroom. I also enjoyed the Planck's Room work sheet questions that can be printed. It was full of surprises right up to the last Quantum Room!
