Standard issue for all new employees here includes a copy of Code Complete and a digital stopwatch (gotta make things fast).
I thought that might be fun. So I wrote a quick and simple application (so simple that even the screenshot weighs more than the application zipped) that allows you to specify the task you're working on and runs a digital clock kind-of thingie in front of you.
It might be useful as well as fun to challenge yourself to compete and see how much time it takes for you to implement a new feature, fix a bug, or do an otherwise monotonous task. Enjoy!
