A few months ago I realized I could not type efficiently. I had to check the keyboard every now and then. Since I spend a lot of time in front of the screen, it's a problem. Typing faster means it would be more comfortable to work.
I spent some time using a few software and webapps to improve my speed. I have also switched my keyboard to COLEMAK since the QWERTY layout is not so good. After a few weeks using typeracer.com, I had ideas to improve the concept. Here's my stuff. Do you like it?
