I'm Ed Caspersen
I build things

That's what I do. I build and I know things. I'm the founder and sole proprietor of Vagabond Burro LLC, where my apps now live. Open-source tools, and the occasional thing nobody asked for. When the screen's off, I'm behind a camera or an instrument.

Open source

Free, open tools I build in the open, for shaders, photography, and music.
