Yeah, I kind of like it too. Very raw, but well thought out. The hard drive speakers were a superb touch. I'd never thought of using a printer as a drum machine either, but now I see it, it makes sense. Genuinely, I did think of using the bass sound from a scanner before. An old Canon one we had kicking around at the time I had a Yamaha sampler as it had a very nice constant low tone. Amazing to see someone actually doing it.
Happy? That was my first thought to the article title - they're bloody miserable sods! But that was very impressive!
