What's this about?
Mollick's two public Astra demos: a historically-grounded walkable simulation of the Library of Alexandria, and a procedural ocean with animal behavior, built on top of an open single-file storm generator.
What exactly is "procedural" generation?
Content computed from rules and seeds rather than hand-made assets — infinite variation from finite code. The ocean demo extends someone else's open project, which is the point: the model reads, understands and builds on found code.
Why is this worth noting?
These are what one-prompt-and-iterate development looks like at current frontier quality — and they're both browsable links, not screenshots, which is Mollick's stated media strategy (see his "nobody clicks links" post — the irony is intentional).
