If you like rocking around your bedroom playing air guitar , then scientists have just the thing to make this even more fun.
It's a shirt that picks up the crazy movements you make as you strum your pretend guitar and turns them into sounds with help from a computer.
It's done using sensors built into the t-shirt, which send signals to the computer, creating the player's tune.
The inventors say you don't have to be a musical expert to enjoy the shirt.
"It's an easy-to-use, virtual instrument that allows real-time music making," said one of the scientists, Richard Helmer.
"It allows you to jump around and the sound generated is just like an original mp3."
The shirt was invented by a team in Australia, who now hope to turn their talents to making stuff to help people exercise or recover from injuries, using the same technology.
