# Discrete and Computational Geometry Projects

At Harvey Mudd, I’m taking a cool class called “Discrete and Computational Geometry”, a special topics course taught by Professor Satyan Devadoss. It’s a very interesting class. In lieu of normal problem sets, we instead do a bunch of group projects, each one very freeform. The basic instructions are “go make something related to this class”. Here are a couple of the projects my group made:

# Shift Clock

I'm really happy with how this experiment turned out. It's a clock that spells out the time with squares, and then shifts those squares into their new positions whenever the time changes. It draws the time text into a hidden tiny canvas element at each minute, then uses getImageData to extract the individual pixels. Any pixel that has been drawn with an alpha > 0.5 is set as a destination for the next squares animation. The animations themselves are performed using d3.js.

The picture above is of the black-on-white version. There is also a grey-on-black version, if you prefer that color scheme.
