I like this - a bit like tomato.es - you enter the name of the project after you complete a pomodoro and it lists the ones you did today. Good if you want to track where your pomodori went for the day rather than just '7 today'.

It can be quite small and unobtrusive, or even just expand out/in when you click on the "Successes // X today" bit.

E.g. this is what it looks like on tomato.es, it only takes up a small part of the screen.

Something a bit like 'Abel township' in 'Zombies, Run': you get say 10 'materials' for every 25 minutes you focus (bonus for X in a row). Then at the cost of a certain amount of materials you can add buildings to your city and upgrade them. e.g. a house adds 10 population, a school requires 100 population, a level 2 house can add an additional 10 population, etc etc.
