@remko

TIME&DATE could also be interesting (see https://forth-standard.org/standard/facility/TIMEandDATE) for example to make less predicable results.

The "Plant" in Thurtle always gives the same pattern.

@farvardin That's a good one, but since this depends on the environment (and I want to keep the dependencies of the core minimal), I'm probably going to add it to the JavaScript wrapper, and provide an easy way to load these extensions from within JavaScript.

@remko I don't really know how WA works, but I was thinking to use it with JS, since the browser has access to the system's clock :)

@farvardin Not sure I want to add TIME&DATE anymore (i want to keep the system dependency as simple as possible, and computing time and date is not trivial), but for the purpose of bringing randomness into the system, I added a RANDOM word (and adapted the Plant example).

@remko sure, random will probably be even more useful for most people, and given thurtle's goal!
