This Aussie is a real master at achieving the "miniature set" look in his videos.
Bathtub IV Looks way too much like old fashioned stop motion animation of a little table top set, but it's real folks and a real world being shown to us in a way we're not normally used to seeing.
Also try searching youtube for stuff by "milapse"..some excellent tutorials in there (Ross Ching lists him as an inspiration for his work.)
Ching's using Canons with Canon's own intervalometers. Nikon DSLR owners aren't so lucky, as Nikon's own intervalometer is pricey, and only works on some models. No intervalometer for D40, 40x, 50, 50, or 70. (But see below.) The D70s and D80 use a different one from the rest of the Nikons, and the D100 only works with one when the battery grip is added. The other model, however is compatible with the D100 w/grip), D200, D300, D90, D700 and all the F Nikons from the F4 to F6.
There are a few Chinese vendors on ebay selling intervalometers to work for a ton less than Nikon's own, and from what I've read, so a great job. (About $40 with shipping)
One of those, plus a cheap Chinese Nikon-clone compatible IR controller, hacked together (intervalometer's camera cord plug hacked off and the 2 wires soldered to the pads the push button closes on the remote control) makes a under $50 intervalometer that'll run any Nikon that uses an IR remote. Just mount the thing in front of the camera on the tripod, but our of the way of the lens.)
Even the trick motorized pan and tilt tripod is a common item....it's the tripod head and mount for the Meade 2000 series telescopes. Just add a steel "L" bracket to mount the camera instead of the scope. (Available with the telescope new for $150 on ebay, plus shipping.)
If only the patience to sit through hours of the camera making hundreds of photos, once every 5-10 seconds for hours on end were cheap. :)
