I gave it a try, and the on-line studio managed to one-shot a convincing prototype of a type of drawing program which I've asked LLM App-Dev tools to create in the past and which heretofore, none has managed anything resembling a workable effort, so colour me impressed.

So, I've downloaded it, and unless I overcome a couple of hurdles in a current project in SpiderBasic, I know what I'm doing this weekend.... (porting what I've done to this and finishing it in Python).
