About 20 years ago I wrote a little program to turn my own standard keyboard into something I could type on one hand with. It's basically just T9, with every basic letter key bound to two letters instead of one. (The mirror counterpart from the other side of the keyboard.)

It's a shit demo from college and I always wanted to share the concept but never made it presentable.
