Streaming real time images from Twitter during the London Olympics was fun. Camelympics turned out to be an interesting(mostly for the developers) project:
Claus Ibsen (the core Camel rider) blogged about it and it was mentioned on DZone.
Bruno Borges' talk on "Leverage Enterprise Integration Patterns with Apache Camel and Twitter" at JavaOne conference (slides available here) had the demo inspired by Camelympics.
Websockets are not widely supported yet. IE doesnt support them, mobile browsers doesn't support them. The only Android browser I found with websocket support is Dolphin Broser, but then 3G networks are not fast enoug to cope with real time (even throttled) image streaming. It needs at least another year before Websockets become widely useful.
Twitter introduced new Developer Rules and limits to make life harder.
As Bruno proved during the live Twitter demo at JavaOne conference, Twitter is the world's largest nsfw photo streaming service, and there is nothing you can do about it (yet).
Extented the application, so in addition to Twitter it also retrieves photos from Instagram and Tumblr in "real time". Tumblr doesn't have a real time api, and Instagram's real time api, based on tags is useless. So I had to come up with some clever ways to give the same real experience for the user.
Added search functionality. It is actually a real time filtering functionality - the application will monitor Twitter, Instagram and Tumblr for photos with a given tag and stream only these images as soon as they are posted. I am not aware of other application doing it.
Decided to replace the custom styling with Bootstrap, it just works.
