Somewhere between 2001-2004, I was laying in bed one night, flipping through TV stations, when I came across rage (Australia's late night music show) who were playing a music video for a rather nice sounding song.
In it, the band (who were comprised of about 3-4 people) were playing in a rather Gary Numan-esque scene (dark, spacey scene with glowing florescent lights around). On the drumkit, amps and possibly other equipment, they had what I assumed was the band logo -- a (possibly rainbow coloured and upside down) triangle. The group played a rather slow synth-heavy song and whenever they hit a particularly long note, one of the triangles would slowly emerge from the bass drum or the amp and fly towards the screen, eventually fading out when it took up the whole screen.
I do recall seeing a singer, so I believe there were lyrics, although I don't remember them.
