Curious to learn more? We're publishing a series of notes about our experiments. Our first note introduces how amb values work and why they improve on existing spreadsheets: www.inkandswitch.com/ambsheets/

I spent about 45 minutes making this. After I showed it to Alan, he gave me an internship at VPRI, working on the STEPS project. A couple of months later, he would be co-advising my Ph.D.
Best ROI *ever* on writing a computer program.

The hero of this story is Etoys' "color sees" tile.
When the wire's red sensor sees the color yellow, the wire turns yellow. Otherwise, it turns black.
You can make AND, OR, NOT gates the same way -- it's nothing that a 5th-grader would have trouble making on their own.

@chrisshank.com My Sketchpad triggers haptic feedback in the Pencil when the cursor snaps to a line / point / etc. and it's quite tasty! Doing it via the I&S wrapper for now... it will be cool when that functionality is available via browser APIs.

It's a recreation of Ivan Sutherland's Sketchpad that I've been working on. It's not quite ready yet, but I'm making progress!

Love this!! Thanks for giving us a look behind the curtain, super interesting @rob-sheridan.com :)

We tried all kinds of things, but my memory is fuzzy. At some point I found a bug report and this, and the OP was told that it wasn't a bug :/
Anyway, if you can simultaneous touch and pencil interactions working in the web browser (maybe in a tiny demo?) we'd love to se it!

We get around this by capturing the touch and pencil events in the wrapper application (which is a native iPad app written in Swift so it doesn't have this limitation) and sending them (as JSON objects) to the JS code that's running in the WebView.

IIRC, the browser (even when it's running in a WebView) purposely ignores pencil events when touch events are going on and vice-versa. There's no technical reason for this -- the people in charge decided that interfaces like the one you see in my video would be too confusing / error-prone.
