Here are a few websites that might decrease BOREDOM
Fridge Magnet Artist - This is a fun little game that allows you to collaborate with other to make weird yet wonderful magnet sentences. This is definitely worth checking out.
iSketch - A fun game where you are in a lobby with one person drawing a word that is randomly generated and the rest of the lobby trying to guess the word. The 'Sketcher' is randomly selected every round.
Multiplayer Piano - This is an entertaining web app that allows you to play the piano using you keyboard or mouse with others. It even has MIDI support! (Sometimes this does not work on Google Chrome).
Screaming Beans - It is probably better that you have a look at this one and decide for yourself it is a bit weird yet it is still entertaining and you are sure to enjoy it. (Volume is required so headphones would be preferable).
Silk Art - This is an interesting line generator that can make even the worst of artists look like they have skill. The things you can do with this are stunningly beautiful.
Sketch Swap - Draw something rubbish (or nice), submit and receive a sketch from another person. A touchscreen tablet make your drawings look slightly nicer than those draw with a mouse.
