One of my latest personal projects and though it is still very much an on going project I am still very proud of where it is at.
The goal of uKoel is to create a Jukebox using a Twitter hashtag. Simply enter a unique hashtag in on the Jukebox page and start tweeting song requests. Have your friends join in and watch your playlist grow. Using Youbtube as the source for the music the song choices are almost endless. There is also a built in song search tool in case you want to make sure to find the right song to tweet.
