This countdown uses the classic Towers of Hanoi problem to display a countdown to a specific date and time. When all the disks have been stacked on the rightmost peg the event has started! The number of disks required is calculated by determining the number of moves needed to perform about one move per second. GWT 2.1 was used to perform all logic, while webkit keyframes were used to perform animations.
Below are some controls to allow you to choose the start and end date and time for the countdown. Start time is when you want the countdown to begin, and end time is when you'd like the countdown to end. If start time is some date and time later then the system clock then it is ignored and "now" is used instead.
