This is the info I looking for.

Say what.
For now I start to study how to load OMeta.
I use for this my http://squeakros.org/CuiSantafesino.2.zip fork as is more
Squeak compatible.
Try and see what you could do with only 509 classes and 2.8 MB size.
Only possible thanks to Juan, of course.
But haves DragAndDrop, could read simple Squeak Morphs, and could try to
load Squeak 4.4 to 3.9 older classes which not was in the image.

The weird lessons was submitted here as this is a cool list with smart
people.

And we have Juan for advice ....
