My brother Dan created a weather forecasting website for astronomers and astrophotographers using forecast data from CMC and NOAA. I contributed a coordinate system transformation and grid scaling algorithm to the project for implementing real-time linear interpolation on tile visuals.

roulette curves

Dynamic and static visualizations of hypotrochoid and epitrochoid (spirograph) curves. Set the ratio of circle (gear) radii and the location of the trace point and watch the curves form as they are drawn. Also, generate a single curve or overlay multiple curves to print and color!
