spinning, spiral object in austin

• When: March 8, 2013
• Where: Austin
• What: Floating, spinning spiral object

A UFO-collecting YouTube account has uploaded a video of a supposed sighting in Austin, but details of who shot it are not available (yet). Shown in the video is a spiral-shaped object, spinning and floating through the sky. It seems like it could be a light or hologram being projected into the sky, but it's definitely not a balloon, bird, or Chinese lantern. Any guesses of what we're seeing here? SXSW got underway shortly after this sighting, so it could be related to a media event of some sort.
