HyperSpace Express is Steve Savitzky's little indie/geek multimedia publishing company. Its only current product is Steve's CD, Coffee, Computers, and Song! An earlier product line, now out of print, was a series of file translation and transfer products for Perkin-Elmer spectophotometers. You can find those (eventually), plus current open-source projects, on GitHub.
Current CD projects include Steve's next CD, Amethyst Rose, and a CD for the folk duo Lookingglass Folk. Current open-source software projects include MakeStuff (the software used for my CDs, songbooks, and websites) and Honu, my one-line Linux setup system.
