Light trails at twilight

Now here's an oddity...

On my way to the car park after work I took it into my head to try using the Slow Shutter app's light trails setting on the traffic on the main road, even though it wasn't dark yet but people had their lights on.

This was an 8-second capture, hand held, and then put through Photoforge's Dreamy filter which has darkened it a bit and brought out he colours more, while softening it slightly. The unprocessed shot almost looks like it was painted, this slightly less so. I particularly like the "ghost" lamp post!
