I've been playing it. I leave it on for 8-hour periods in the far corner of my desktop. It just spins away and sings at me once in a while. The A-K keys on the keyboard (and the Z-, keys) play notes, like a single octave scale. You can zoom out all the way to space. If you want. Or, you know. Whatever.
This is my mountain. It was snowing a while back, and the snow has now melted. The only remarkable thing I've noticed is that there's this big blue growth on the side of the mountain.
Now if the mountain is indeed a metaphor for my actual self, and that tumor is a metaphor for... a tumor, it's possible my mountain has some kind of cancer. Glowing, pulsating blue cancer.
I'll keep you posted, I'm sure you'll be glued to the screen waiting to hear more on this one.
