Can any (Physicist) explain this laser-weirdness that I'm seeing? Answered

I've got some cheap-o red-lasers. Up close on surfaces I see what looks like old-fashioned monochrome TV static in miniature* (and red). Other people see it too, I think it's some kind of "Quantum-noise" but would like other opinions. L *I don't like looking at it - it reminds me of this.

Robot having trouble resizing gifs?

I just noticed that the title gif for AndyGadget's Piecax the poltergeist has lost quality when resized by Robot. The large and medium ones which haven't been resized appear fine but the small and thumb ones have been degraded. I wonder if this is an issue for all gifs? I wouldn't know where to look for others, this one in my CD ible doesn't seem affected but it's just black and white unlike Andy's image which is more complicated. But then... I uploaded this one and it and it has the same problem. Where robot hasn't had to reduce the size it's fine, but when it resizes (small and thumb) some errors are introduced.
