How many computers are you using? Real? Virtual?

Are you using the Racket web server, Apache or other? Photos?

long to write in C? Are you processing the images in Racket or using a

(A comparison of a pixelation with a naive algorithms and a better
algorithm would be nice, but it can be a lot of work and perhaps it's
part of the secret sauce.)

Problem with the speed? Memory use? Garbage collection?

Mix this with pixelated pictures like in
https://www.youpatch.com/about/, pictures make it easier to read and
make it more interesting. Pixelated kittens are always welcome :).

Some additional ideas: (Not sure if they are very useful.)
