I am hooked on a few things right now:
a good site for doodle junkies. the website is good but the blog is fun too.. they post new artists every once and awhile and it is quite inspiring
people send in their secrets on homemade postcards. intriguing, scary, funny.. all of the above.
a good alternative to sudoku, free cell and other time wasters.. donates a grain of rice per word or something to that effect.
Interesting facts about voter rights for students and the fight to uphold them.
another cool art project. they post photos of found stuff.. it is really interesting.
