We're refreshing the website and replacing as many of the images as we can with line art diagrams. This fits the vibe better, they're easier to maintain, and they're hundreds of bytes instead of tens of thousands.
Lucy is using the delightful Monodraw for this and I thought I'd give it a shout-out. If you have any need to draw ASCII diagrams and you're on a Mac, you'd be mad not to use it.
There's a free trial, and it's ten measly dollars to buy.
