I took a Windows screensaver lightspeed effect and drew it on a panel every 60ms. It's at layer 10 (it might be better if I drew it before entities are draw). Anyway, it kills the framerate (6 FPS) so is pretty much a dead end. It also looks strange because the "stars" only move straight at the viewer and don't curve when moving sharply up/down/left/right.

I think I'm still a 2D programmer in a 3D world.

You can see some of the lightspeed effect stars in front of the particle effect. The stars in the background are a skysphere and the "streaky" stars are the lightspeed effect.
