Image EQ (Equalizer)

An audio EQ lets you adjust the volume of different frequency bands to adjust the tone of a sound. This lets you adjust the "volume" of different spatial frequencies in an image.

Bass Catalog + Practice App

Tool to make my practice workflow easier: listing all the songs I've learned, linking the actual songs for accompaniment, and adding a dually automatic/programmable metronome. A much more convenient way for me to revisit a song and practice to tempo from anywhere.

Radial Drum Sequencer

A circular drum machine where each ring is a different sound. Scroll or press +/- while over a ring to change subdivisions, SHIFT+drag the white sliders to rotate rings, click cells to make patterns. Polyrhythms arise naturally.

Data Visualizations

Different doodles of visualizations I make, and showcasing visualizations I find interesting.
