MaToMaTo (http://www.vivasoftware.it/PomodoroTimer/MaToMaTo/) is an animated Pomodoro timer compatible with MS-Windows, and like most pomodoro timers, a freeware.
Unlike most pomodoro timers that work in the background or remain in the browser bar, MaToMaTa stays on top of all windows, allowing for easy view.
MaToMaTo scores on its simplicity and attractiveness. The animated display swings every second for the first 20 minutes of the pomodoro, and pulse like a tomato-heart during the last five minutes. It does not make any noise, making it ideal for public spaces. To top it all, installation is easy and requires only unzipping the downloaded file and starting the .exe file.
On the other side, MaTomaTo has no activity manager, and just acts as a timer. MaToMaTo requires .Net 3.5 to run it.
