A simple portfolio app for small selections of images/movies/documents (whatever!) built using the drop.io Ruby API. It is a Sinatra App, which allows for easy readability of the whole codebase in a single controller-type file, with a couple of views for the HTML and Javascript. (Take a look at dropfolio.rb for all the meaty drop.io related stuff)
Configuration is easy, just head over to http://api.drop.io and grab a free developer key. Enter this key in dropfolio.rb where it says:
Dropio::Config.api_key = "ENTER_YOUR_DROPIO_API_KEY_HERE" # go to http://api.drop.io to get a free developer key
This project already has a config.ru file for easy deployment to Heroku. For more info on how easy it is to hack on Heroku running Sinatra, check out this post from the folks at Heroku. Sah-weet!
