We recently updated the Vischeck website properly after 25 years. Everything is now client-side Javascript and the color vision simulations, Daltonize correction and infant vision simulations are all in the same place. Full GPL source code is available on
An earlier iteration of the same block is imo more impressive in its creativity - https://www.youtube.com/watch?v=6wBrOV2FJM8&t=720 - such an unexpected and yet completely natural extension of the brick set.
Thank you Uncle Dane. Uncletopia is my happy place. I know that people say that the solutions to lots of problems are political not technical. But I think in this case there really are simple technical fixes that would be trivial to implement and very effective. Off to W+M1 right now...
I >think< that this will enable more accurate magnetometers (see OPM-MEG and atomic clock magnetometers). Which can be used, among other things, for measuring neuronal activity.
Weird use case: sending EEG trigger codes through a Dpixx interface to an old ANT amplifier requires the codes to be Morton numbers. It took us a loooong time to work that out :)
