I went back in time 150 million years and recorded this with binaural microphones. Two sauropods are talking to each other across a lake while many other dinosaurs occasionally call out. Three at once start out the recording. Listen with headphones to get the full effect. Painting is by Gerhard Boeggemann; image licensed under the Creative Commons Attribution ShareAlike 2.5 License.

I made this when I was on Triton, Neptune's largest moon, in 2085 AD. It is time-lapse (3000x real-time) looking West, 99 km West of Mahilani Plume, over the course of two Triton days (about 12 days Earth-time). Because of certain aspects of Triton's tilt and rotation and because of its orbital inclination of 157° up above and down below Neptune in retrograde, from this vantage point Neptune seems to set and then rise over and over in a loop with moons spinning round it going the opposite way we are. You'll see two peeks of our distant sun on the right. The galaxy, our Milky Way, goes by in the background twice. Music is from a 2007 piece titled "Lives of the Bloated Gas Giant Suns". Made using Starry Night Pro 4.
