Here is a fun collection of messages found on parts of a computer, invisible to the naked eye:

Our search has led to a new collection of photomicrographs (photographs taken through a microscope) featuring many of the interesting silicon creatures and other doodling scribbled onto integrated circuits by engineers when they were designing computer chip masks. […] Engineers designing modern computer chips have a very rich sense of humor as you will discover when you visit our Silicon Creatures Gallery that we keep corralled in the Silicon Zoo. We hope you enjoy your adventure!

There seem to be a lot of Texas flags, and I thought the disclaimer and the warning were amusing.

This reminds me of the Amiga 1000, which had signatures of the designers on the inside of the case, “including the pawprint of Jay Miner’s dog Mitchy”.

Are there any puzzles or ciphers? Will these become the cave paintings of our generation?
