This is my spin on the WebOS challenge. I went a bit off the hook - since the requirements did not specify that I must follow the guide, I am doing something a bit more similar to a real OS instead of a fancy web page - though it's still a web OS!
Ever get sitting there, staring at a lab report or a 4-page essay you need to do, and you just hit a block? This helps with that! The Lockininator is a simple HTML web app that will let you select the minimum and maximum amount of time you want to work for and rest for, and then - YOU GAMBLE!!! You gamble for how long to work, and then gamble for how long of a break you get. The break will be weighted by how long you worked, so longer grinding sessions are more likely to get longer chill sessions.
