I learned monte carlos in Excel circa twenty years ago and spreadsheets are still my goto for building sims.

What am I missing?

I'm looking for something simple, more visual, agent based, more shareable.

Something where I can get a decent shareable sim going in 10 minutes, and maybe something worth publishing in a day.

I can build games in Unity, but that's a bit heavy.

What are the lightweight sim tools?

I'm excited about https://hash.ai/. Are there other things out there?
