The Makey Makey is pretty well known in maker circles. My use has been limited to creating new ways for students to create interfaces on computers but there are new implementations that include the use of Little Bits and other tools. The Makey Makey Go is tiny and I keep coming up with thoughts for using it as well. There are a lot of potential maker opportunities with this tool. Typically I satisfy my curiosity about conductivity labs by having kids play with this tool and let their curiosity lead tinkering activities. It is a great place to start something a little complex.
