oh yea I figured it was a random glitch/bug - cuz I've only seen them maybe..twice in the last year or so.
But yea whenever I do I'm like "ZOMG SPARKLIES ARE BACK!!" and while I've asked, I've never had anyone come out and see if they can see them at the same time I can or if its just me - heh.
Last time I saw them yes, there was one over the desk/orb thing in the "sparkley" Helian room, and there was one in my entrance chamber which is a Helian Scale Forge, it was near the waterfall.
Its just so interesting how they look like, handdrawn in paint, when looked at with the background of the rest of the game - lol.
