The interface needs some work if you're not familiar with block based programming environments. Dropping things in place is a bit difficult compared to Scratch or Snap.

> Some blocks I can attach to the bottom of "run this program" block and they clearly run.

The blocks with a square side are commands you can attach to each other to make a program. The round blocks go in the round slots on other blocks.

> The screen is two dimensional so I was expecting to be able to put processing blocks anywhere. Sure I can but they do nothing.

You can click on them to run them without them being connected to a "run this" block. Whatever has a yellow outline is running.

Thank you. I got a little further this time. The UI needs a LOT of work to make it friendlier. It's difficult to enter numerical values, and often the values just go blank.

I suppose there's a reason node editors use a block and line interface mainly.

I'd actually prefer a tree-structured approach, where you could turn a subgraph into a single block, allowing you to structure appropriately.
