This is what the world of bioengineering has given us today: a cross between The Empire Strikes Back and the Princess Bride. Medgadget reports:
We’re not exactly sure about the potential advantages of having a sixth digit on our hand (aside from being able to play some crazy guitar licks), but a student at San Francisco State University, who also works for DIY website Instructables, decided to see what it would be like. He created a special glove with a robotic sixth finger that curls when he flexes the muscles in his wrist and arm.
Neat looking project.
