Picked up this RBTA from another member last night. at first I thought it was purple tipped, but while moving my head around i noticed the tips moved with my viewpoint. My RBTA + my LEDS + is causing an optical illusion to make it look purple tipped, it looks like each tip has a plasma ball at the end or something. surprisingly it shows up on camera. It's not my bow front because I see them from the side too, the dots just dont protrude as much from the side panes.
the balls are similar to this
