The Internet has tons of fun things to do. They’ll put a smile on your face. Here are 5 digital diversions that will definitely lessen your productivity.

JamLegend – Guitar Hero set off a music video game craze. But you don’t need a gaming console to have that experience. Just pick up your keyboard and head to JamLegend. Play instantly, or sign up to track your stats. Independent artists submit new songs regularly.

Masterpiece Yourself – Usually, photo-editing software is used to improve photographs. But making a joke of them is even better. This site lets you insert people into famous paintings. Put your wife or sister’s face on the Mona Lisa—or your husband or brother’s. Then, just laugh yourself silly. Be sure to e-mail off your creations. These are too good not to share.

TinyTrials – Minigames are just simple and compact video games. But what are microgames? These are tiny games that only last a few seconds. Put dozens of these back to back, and you get TinyTrials. It’s surprisingly addictive. There’s only one thing to do and almost no instructions. Here’s a hint: watch the screen. If you see a mouse icon before a game starts, that means you have to use your mouse. Ditto for the keyboard icon.
