I propose to add something like the following to the 'welcome workspace'.
At the bottom, 'call to action :-) ,
cf Squeak web site discussion thread.

The desktop background shows an prime spiral. Natural numbers are arranged in a spiral in a rectangular grid. The 1 is at the center. Primes are marked with a dot.
To see how this is done in Squeak Smalltalk a) select the following code, b) bring up the context menu and c) choose 'do it'.
Display restoreAfter: [ size := 400 squared. primes := (Integer primesUpTo: size) asSet. step := 1. length := 1. pen := Pen new turn: 90. [step < size] whileTrue: [ 2 timesRepeat: [ length timesRepeat: [ pen fillColor: ((primes includes: step) ifTrue: [Color black] ifFalse: [Color white]). pen go: 1. step := step + 1]. pen turn: -90]. length := length + 1]].

So the question is, do we get the Ulam spiral creation code snippet included in Squeak 4.4?
You ask 4.4's release manager, who says "yes! and I'd like some covering text too please!"

Things which it illustrates are
- The compactness of the Smalltalk language
- How to modify code in a Workspace and execute it with 'do it'.
- The fact that you do not need to have 'deep' knowledge of Smalltalk
in order to adapt a piece of code. 4) It is like a 'poem'. A short self contained nice piece of code.
- Code can be executed directly in the mail window. Oh wait, that is
just me - the last Celeste user ;-)
