Comment The Original Article on eXtreme Feedback Devices (Score 2, Informative) 249
Wow, JavaLavaLamps are getting their 15 minutes of fame on Slashdot - I am bubbling with pride.
As the original implementor (AFAIK) of the unholy and unlikely combination of CruiseControl + Java(TM) + X10 + Lava (TM) Lamps, and the author of the article in Mike Clark's book, I am thrilled (and a bit concerned that this will be THE contribution to the computing I will be remembered for.)
In any case, JavaLavaLamps are just one of the eXtreme Feedback Devices (XFDs) I mentioned in the blog that started it all. You can read about XF and see other XFDs at: http://www.developertesting.com/managed_developer_ testing/000036.html. Have fun.
