The Keyboard From Big
It's the keyboard from the classic movie "Big" starring Tom Hanks as a kid! Ok, it's slightly updated as it can connect to iPods, phones and more.
This toe tap piano plays notes as you step on the keys. It's 28 square feet of toe tapping goodness. Run around or even slide on it to make music.
It actually has almost 2 full octaves (14 white keys and 10 black keys) so that you can have 2 people making melodic harmonies. You can also record and play back your compositions and tap along to other songs. You can play music from your iPod, iPhone, Android phone or other MP3 player and play along to that.
