Fluxiom Unleashed!
While in Vancouver BC, I had the privilege of meeting Thomas Fuchs, the guy behind script.aculo.us and mir.aculo.us. His company Wollzelle has just launched their new web service called, fluxiom. I’ve seen the videos and saw him demo some of it at Canada on Rails. The stuff that they’ve trained the browser to do with AJAX is unbelievable and it’s also built on Ruby on Rails! :-)
They are offering a free 30 day trial... so go check it out!
