HotBox is a background application that allows you to make anything on screen full screen! Just press a keystroke and drag a box around whatever you want, and it'll fill your entire monitor.

It works great for things like webpages with videos or flash movies that don't have a full screen button, games you want to play full screen, text or images you want to enlarge, or anything else you might ever want to see become big. Anything that's on the screen can be made full screen, so the possibilities are potentially endless!
