Eric Heumann, a Structural Engineering masters student at the University of Texas at Austin and graduate of Cornell University, is a principal composer of OSIFC and is also responsible for the graphic design of album art and the OSIFC website.

Having no original experience or training in musical theory, he acquired most of his composing skills by studying the styles of his favorite rock artists, incorporating the musical knowledge he possessed as a tubist, and paying close attention to whatever Robert was doing during early osifcing sessions. His early musical ideas required extensive editing and revising by Robert and Andrew, but things slowly improved, and by the time Naked Handgrenade rolled around, his works were being accepted by the band in their original form.

While Andrew was responsible for the artwork of Humanity, this role was handed off to Eric for all subsequent albums. A somewhat death-proof digital camera and some keen photoshop skills allow Eric to develop the imagery you find on most of OSIFC's albums.
