White Noise (greyscale)

haha!

pure, true randomness like this aims to approximate (but doesn't completely - since it is based on prime number divisibility which may or may not have an easy decomposition we have not yet discovered) is not easy to find in nature. this is mathematical, algorithmic. TV snow is the effects of TV picking up "natural" signals, which are far less "random" than these. hence, they have much less entropy. if you analyze them, compared to this, you will find patterns much more prevalent.

I'm SO glad you explained this. I asked a physics major about tv snow once. This guy was far from whacked. He said something like: "It's debris from The Big Bang traveling from the center of the universe." I accepted that and never pursued it furthe…

this stuff is way more intense than television snow,

television snow actually has a really low entropy count.

BUT -- it also takes several minutes to generate one frame on a 1.7GHz machine,

so to get realtime video from this, you'd need a heaping ass huge cluster!

In another place and time - my friends and I had a favorite pastime of sitting and watching television snow for hours & hours & hours

well, I'm like a rainforest person seeing a wristwatch for the first time or something. That is really cool. And I do think I see it in your vispo? The graininess that's there sometimes - but works to give it texture?

i use whitenoise in every digital piece i make, to give it extra texture!

i make it transparent enough so you don't notice it really, but it adds a dimension of craziness to the piture to make it come more to life.

without it, they usually look much "flatter," IMHO.

same thing, just printed and framed (uploading them now)

you can also make colorized "whitenoise" that looks a lot funkier.

this is what people generally think of when they think of "seeing" whitenoise, but you can have colors in it if you use RGB for the picture type instead of greyscale.

I like stuff like this - missed earlier ones you did

i can print a photo for you!

i sent these out a few months back in the form of TV postcards.

i'll hunt down the link for you

woh, am I looking at white noise? Like these ones you can stare at
