I have several tools for doing real assessment and a quite a lot of data
from previous tests on entropy sources, random generators. DakaRand,
Havege, Jytter, Intel RdRand, YubiJSM for example.

Dieharder for example is always installed and ready to go. But Dieharder
takes a long time to run even om Amazon clusters.

The new tool is just a quick way to view possible entropy data and
utilize the abilty of the human brain to detect patterns in images.
Things like bias levels are harder to spot.

I also find it good to be able to show people what randomness looks like
vs things people think are pretty random (a short LFSR chain, an AES
encrypted image with ECB mode, most linear congruential generators for
example).
