Time lapse light effect and timelapse tips

That looks like time lapse with a long shutter speed - long enough to turn each moving light into a streak vs. a point.

Wish I knew what kind of rig they did those moving shots with.

If you're going to play with time lapse, do a lot of tests. SLRs can be pretty flicker-ey, for two reasons. One is that the aperture (wide open when focusing but it closes down for the actual shot) doesn't close with complete accuracy. On Nikons and Canons, do test shots to determine aperture, and then hold down the DOF and lens release buttons at the same time; twist the lens off just a bit - this will "lock" the aperture (to say, f8 or whatever) and it will be truly constant. Even a manual lens acts this way. For me this has killed almost all flicker.

The other is to set your camera to mirror-up, which some bodies have. On a D7000 you choose mirror-up shooting; the mirror (for the prism) lifts into place, the shutter clicks, and the mirror returns... with a slight pause. This eliminates mirror shake on longer exposures.
 
Tip 1: all setting on your camera should be in manual mode to make sure all frames are alike and to provide a smooth clip.

Manual mode won't stop iris flicker. You need to lock the iris at the f-stop you're using. Trust me on this (or try it yourself).
