I came across this product recently which seems to have been intended as a cure for office boredom.
Today’s invention is inspired by that sentiment. It consists of a dance mat laid out in a keyboard arrangement -with responsive areas acting as keys which are large enough to accommodate the toe of a shoe but which cause the mat itself to be no more than say 1sqm in size (allowing it to be dropped on any floor).
This device would communicate with one’s phone and allow messages to be danced out and sent direct to eg Twitter.
The mat might also have one’s friends pictured down one side, enabling them to be selected and eg texted individually.
