Comment on Why and How to Start Your SICP Trekparent

Comments

This works great, with one caveat: the picture language in SICP has built-in primitive images such as "wave" and "rogers".

The DrRacket SICP package has only one primitive image, "einstein".

I had to make do with Einstein. I also discovered afterwards you can copy and paste images directly into DrRacket and pass them round like anything else - you might (very big guess) be able to create the wave and rogers primitives this way.
