Brick Mug: 2011 - ThinkGeek
The Mega Stomp Panic is a weird 'toy invention' type of product that we came up with by starting with a technology, accelerometer based sound activation, and molding it into a product. It plays back various sound effects and background tracks according to how you step and stomp your feet, like robot servo noises or Godzilla destroying a city. It was really hard for me to conceptualize what form the product should take since it's totally new, but the constraints were similar to a pedometer that needs to ride on your hip to sense your gait and footfalls. Multiple people on the team had input into the form, but I pulled all of the sketches and models together to create the final CAD file.
