Here’s a very cool project based on Kay’s Chifir, it asks the question: if I give you this image, are you able to build a working computer to evaluate the code hidden in it.

You and your team of 23rd century archaeologists have been digging for
days with no result, but it seems your efforts have finally been
rewarded. You stand before what looks to be a rusty shipping container
with large letters scratched into its side. The letters read:
"The Archive of Late 20th Century Computing"
Giddy with excitement, you wrench open the door and step inside.
The container is filled with crumbling plastic boxes. Inspecting a
few, they appear to be packed full of optical disks of some
kind. Picking one such disk out at random, you see that it has a label
affixed to the front. Happily you find that you can understand the
text - your study of the languages of the ancients has paid off,
it seems.
Have fun : )
