BarCampLA6 has been pretty cool so far I really liked the MS Surface, because it is a new interface that no one has a use for yet, but yet it shows so much promise. I found Apple seems to be in the surface space too, they have a better idea then MS, inbed the sensors in the LCD.
Amora is a N95 applet that lets you control your Linux system where you can run amorad on Linux. Pretty neat. I could use this for presentations, now it is in Python, maybe can be ported to Windows and Mac.
