Aleph Null is best viewed by the light of a full moon. Or near full moon. Same with the set of stills I made. I mean they do like a bit of darkness.
If you’re using a PC, I’d recommend Chrome to view Aleph Null. At least on my machine, Chrome provides the smoothest performance. Firefox provides a similarly high framerate, but is a bit jerky from time to time. Internet Explorer kind of sucks. On the Mac, Chrome, Firefox, and Safari seem to be fine.
