Mysterious Pink Floating Orbs observed in PlayStation Home Central Plaza.

It is recommended to watch this video in High Quality (HQ) Mode. Let it fully load and then press play so as to minimize dropped frames.

I noticed them months ago (even before Xi started) but thought nothing of it until I saw one up close as it floated across the camera. Originally thought of as flower petals or floating plant debris, closer inspection reveals they are something unnatural in the Home environment.

The orbs are pink in color and look like tiny lightening balls. The floating orbs be observed from far away and occasionally float directly across the camera. They tend to manifest near trees and in shaded areas. As of now, their appearance and disappearance is thought to be random.

Most easily observed by sitting in the Central Plaza on a bench and remaining still (camera must be motionless too).

They have only been observed in the PlayStation Home Central Plaza and do not appear to manifest at any other location within PlayStation Home.

What are these strange floating pink orbs? Technical error, purposeful design, Xi related or something else?
