Random Number Gen update

Things working out better now. Scaling numbers works very well, no bias in the tests!
Very happy now!

Random Number Generator

Okay, so I'm a nerd. Sue me.

I have been working on and off for a year now on a random number generator based on the thermal noise of a resister.

Small sample of data:

Dec Number: 8
Units: 1250000
1  156533   0.180792548536
2  155512  -0.474561448634
3  156449   0.127198000626
4  156057  -0.123672760594
5  156478   0.145707383786
6  156332   0.0524524729422
7  156347   0.0620414846463
8  156292   0.0268727765977


Dec Number: 4
Units: 2500000
1  625304   0.0486163530059
2  625957   0.152885901108
3  624058  -0.150947508084
4  624681  -0.0510660641191


The data so far looks really good and is passing the nist tests.

Hopefully soon I will have a real time True Random Number source for the gamers out there!

Round Chamber Geomorph Set A

My fist complete 5x5 geomorph set is complete.

The compressed tgz file contains all the individual tiff files. Sorry for the change, but png was not working out well.

Round Chambers: download

On a side note, this is harder than I thought it would be. :)

Geomorph Update

After taking a look at all the geomorphs that I've made in photoshop so far, I have come to a conclusion - I don't like them!

So I am starting over. This time with 5x5 grids. Still at 100dpi. These grids fit nicely into the 100x100 so as I gain more experience designing these little gems they should work nicely into the overall set.

Some of the rules I have come up with so far.

• For every open area that joins to another open area - 5 other tiles must be made before moving to a new base pattern. 
• 2 pixel wide walls
