Thanks for this! Re shoelace vs Heron – can you point me to a reference? A lot of these examples are built on examples by other folks, so it's quite...

Amazing, thank you! Let me dig into this when I have a minute and will update the tutorial

Getting the point of collision would be super easy for some of these (point/point, for example) but very difficult for most of them. The math gets way more complex and...

Ah, those will actually be really easy! If you look in the collision functions, they give us the `x/y` coordinates. I don't send them back to the main `draw()` but...

Ditto your other issue: thanks for the suggestion! Broad-phase collision is another one I've been looking into. Any suggestions for improving performance would be very welcome!

Hmm that would be really tricky. You could divide the collision into several steps: - Four circle/circle tests, one for each corner of the rectangle - Two circle/rect tests, one...

I'm running 10.11.6 (El Capitan) on an early-2013 MacBook Pro Retina. It's a super weird, intermittent problem, but I'll keep an eye out and try control when it happens again.

Ok, it finally happened again (hooray?). Using `ctrl` versions of the shortcuts does not work. However, I did notice that it highlights the menu that contains that shortcut, just doesn't...

@benfry – can't remember for sure, but I think command? Hard to test, since it happens irregularly. When it happens again, I'll test that and the window thing.

Hmm, I think it's due to a change in gensim. [This post](https://stackoverflow.com/a/35641434/1167783) seems to suggest you have to change the syntax for accessing the `vocab`. Can you try changing the...
