A twitter-based captioning tool is under development. Re-Tweeted messages are selected and highlighted. The system is http://rcpt.cc. Project Information page is available in English. P.S. The feed function of my blog system was something wrong. Now I tested and http://nishimotz.com/feed/rss2/ seems OK.
I am developing a service called orpheus_tw. Japanese songs composed by the automatic composition system “Orpheus” (a research project at the University of Tokyo) can be shared with the followers of a Twitter account @orpheus_tw. This service was built with Ruby and Rails, and hosted by Heroku. Additional “delayed job” option is also used.
