This is part of the Two Weeks of Code.
A simple one today: a little game built to test the accuracy of your reactions. Start counting down from 7 and hide the countdown timer with two seconds to go: can you hit it on zero? Me… not all that often, to be honest.
This was really built to play with HTML5′s appcache to see about building things that work offline and how you go about bookmarking them andthen using them without network.
