Check this out - it might look like a real finger at a glance, but it's a fake finger with a twist.
Finnish computer programmer Jerry Jalava had to have part of a finger removed after a motorbike accident, so he made a fake finger that doubles as a computer memory stick.
By peeling back the 'nail' and plugging it into the USB drive on his computer he can use it to store files, photos and films.
It would be a bit awkward to have your hand stuck to the side of a computer like this all the time though...
So Jerry's designed the finger so he can take it off and leave it in the computer while he's working!
And he's already working on an upgrade for his hi-tech digit, which will have a removable fingertip and allow more storage and wireless technology.
He says he got the idea after the doctors who treated him joked that he should have a USB "finger drive" after finding out he was a software developer.
