In 1710, Bartolomeo Cristofori took the harpsichord and created the gravicembali col piano e forte (familiarly called the pianoforte).
It was a revolutionary change that affected music composers from Bach to Marvin Hamlisch. It took another Italian, electronic artist Remo Saraceni, to create the newest variation on the theme with The Wallking Piano(TM).

"I wanted to take the piano, a conventional instrument that was invented by another Italian, and remove all its seriousness and austerity and make it an instrument that you can walk across" - Mr. Saraceni said. "I wanted to make technology playful and utilitarian at the same time.
A 3-years-old can jump on the piano, and a 90-years-old man can walk on it".
