As the title says, this originally started as an experimentation of what a phaser could do. I was impressed. Phasers are awesome. I tried making a longer song, but it somehow just failed, so I stayed with this (simple) loop.
It's iterated 3 times because the seamless looping requires the phasers to be synced, which I can't do, so I rendered the whole loop three times to give an idea of what is like when they can just continue.
