I don't have quite enough room between the weight machine, elliptical and where I'm shooting to keep the edges totally clean. A lot of the shots either have something on the side cutting the lines or the expansion groove in the floor does it. Either way, if I had a larger space I could do a lot better.
Can't do it in the house because the dog goes nuts chasing the laser, and I'd have to wait for night so the living room was dark. But, the living room floor would be perfect, plenty of space in there.
The first one was actually brown and blue, the main being brown and the streaks blue. The gel I was using was brownish, and I didn't quite cover the whole light. So, the brown (blue in the shot) lit the main lines, and the uncovered light (was blue in the original) gave the extra streaks. I changes the colors in post to blue and green.
