在自己的T恤上弹吉他

If you find yourself mimicking Jimi Hendrix, Jimmy Page or Joe Bonamassa when their songs come on your iPod, then this is the invention for you.

That's because the latest guitar to hit the market doesn't come with six strings and require an amplifier.

It is in fact a case of slipping on a special T-shirt.

Designed by FauvelKhan, which is run by two engineering graduates from Swansea University, the latest invention is a garment which turns into a playable musical instrument using just a computer and a piece of software.

It works by using barcode technology on the shirt, which is picked up by a webcam as the user's hand passes over the symbol - and then makes notes.

The idea was first developed by company bosses Luke Khan and Warren Fauvel to be used as a promotional object by band The Last Republic.

 Now though it is up for an award in the Music Related Technologies category at the SXSW Accelerator event in Austin, Texas, which takes place this week.

It is the only European entry on the eight strong shortlist.

The invention will be judged by a panel of experts as well as a live audience at the festival which showcases advances in social media, mobile applications and web entertainment.
