Mokoala is a PHP framework that I built specifically for creating small-to-medium web-based applications. Although more than capable of supporting large & complex projects I like to think that it's a great tool for searching, displaying and manipulating data through a set of intuitive objects and methods, ideal for those who want to develop & deploy quickly. You can check out Mokoala.com for images, videos and further information.
Although ShareMyPlaylists.com is my full-time job I consider it to be just as much a personal project as Mokoala. ShareMyPlaylists.com is a companion for Spotify, a music sharing service, giving users the opportunity to navigate the largest collection of Spotify playlists as well as submit their own Spotify playlists.
