I know this may be a silly question, but I can't find anything that explains exactly what it is. I don't have any apps on my DX that refer to it but in the running processes there are always 3-4 programs running with "***.blur.***" in the title so it's on there. I see many of the ROMS talking about having more or less "Blur" or being "Blurry" or being "Blur Free" etc. So at the risk of looking/sounding like a noob, what is "Blur"?
