Light beams - is it Tron? No

I was playing with long exposures last night on my 5d Mark2 and my 85mm f1.2l + a Surefire E1B flashlight.

Basically I setup the camera on a Manfrotto tripod for 20-30 second exposures.  I think walked in front of the camera, turned the flashlight on and pretended it was a lightsaber.  Yes I'm almost for 40.  But I had fun doing it.

I appled a simple lightroom preset and did some cropping.  That's it!  I believe they also call this painting by light.
