Here is a modular tangible programming platform that allows researchers and designers to come up with interactive coding experiences for kids. Project Bloks has a LEGO-like design. It encourages kids to learn about coding through play.
You get pucks to form commands, base boards to read instructions, and a brain board to send instructions via WiFi or Bluetooth to your connected devices. The brain board is built on a Raspberry Pi Zero. More information is available here.
