Make Your Own Holiday Song — With Funk!
This may or may not be the most fun you'll have all day. Depends on if your office is having its holiday party or not.
A custom business card site made this interactive "game" where you can make your own funky Christmas music. It's pretty fun to mess around with.
It's always the same song, but you can do it in thousands of different ways with 20 different "instruments" to choose from.
You may not get anything done the rest of the day. You're welcome!
