16372987 58F3Aa3528 Nice keyboard hack- For programmers like me with wrist pain, I have made a simple keyboard modification that lets you press the Ctrl, Alt, and Shift keys with your thumbs. Just like those expensive $240 Kinesis keyboards, but made using a $30 K’nex building toy. (K’nex is like Lego but uses rods instead of bricks). Link.
