Comment Comment by meta-meta This is very cool! Will definitely project on the ceiling.I am struggling a bit with this explanation though:> ZenithTrack shows a strip of the sky, a thin ribbon, one rice-grain tall, about 2,500 rice-grains long.What does it mean to say "one rice-grain tall"? Is that angular diameter at arm's length? parent meta-meta 5 months ago
