Lying on the ground looking up, during the day. / Lying on the ground looking up, at night (with the flash on).

I never got the constellations to glow, because the only night I was in the lot things ended before it was completely dark and so I didn’t charge them up with a light. The flash shows off the psychotic, invisible, fishing line structure I built to support the tape stars, though. De-installing later this week. What do I do with a 12'x15’ swath of the sky?
