I am very excited about the latest acquisition for our PYP STEM lab -- MaKey MaKeys from SparkFun!
What is the MaKey MaKey? It is marketed as an invention kit for everyone, and practically speaking it is a gadget that connects to your computer that allows to you make original and creative user interfaces for programs. Say, for example, you'd rather tap a banana instead of using your space bar. Simple with a MaKey MaKey! Really, it's probably best to just watch one in action.
Here's a great introduction to the MaKey MaKey, that starts with a cool video:
