The obvious way to go here is something rock-themed, e.g., in the style of a tour shirt or an album cover. Since this is a technology project, you could also bring in a video game angle, e.g., something reminiscent of Guitar Hero or Rock Band games. The design should have an element of fun and playfulness (think Busted Tees, not Ed Hardy).
Some product-relevant visual ideas that could be used as sub-motifs:
- cycles (as in repeated events, not bikes) and, in particular, overlapping cycles (e.g., mandalas, planetary orbits, feedback loops)
- a larger whole comprised of interlocking components (e.g., puzzle pieces, Legos, shipping containers)
- red/green for stop/go, pass/fail
