What if a spreadsheet cell could hold multiple values at the same time?
That's the idea behind Ambsheets, a project I've been working on w/ @geoffreylitt.com at @inkandswitch.com. It's a new spreadsheet that makes it easier for you to explore many possibilities simultaneously.

Logic Game, 2005.
I made this logic circuit simulator to learn Etoys, Alan Kay & co.'s programming language for kids. I represented the state of the wires and logic gates with their "costumes" -- there is no hidden state. This makes the behavior of the circuits visible.

Constraint-Based Spreadsheet, 2014.
An attempt to make spreadsheets more powerful and user-friendly by replacing one-way formulas with multi-way constraints.
Check out the source code (@ohmjs.org inside!) and play with the live demo at github.com/harc/constra...

In this prototype, I also experimented with a purely textual way to bind the values of different number "tokens" to each other. All you had to do was type a variable name immediately after the number. Numbers with the same name would have the same value.

Graphing Scrubbing Calculator, 2013.
I was inspired by @worrydream.com "scrubbing calculator" to explore UIs in which some of the text you type gets widget-like superpowers automatically.

Sketchpad: a truss bridge made out of fixed length constraints. (Note that instantiation followed by dismembering gives you the equivalent of a "paste" in more modern systems.)

Sketchpad: the "dismember" operation inlines an instance into the drawing it's in. This lets you mess with its lines, etc. without changing the master.
In this demo, I make two instances of drawing #2 and dismember the one on the left. The one on the right stays whole.
