hahahaha...that's funny. This guy is the master. There's actually a forum on that site that looks like it has a bunch of good information, but it looks like you're already doing quite well with shooting and processing timelapses. I built a custom motion slider to get the movement in that scene, and nothing beats actual camera movement for the effect that it gives, but I've also faked it in the past by using a zoom effect in After Effects. If you shoot everything at full resolution, you can zoom in to the 1920x1080 frame that you need for the video output and then pan or zoom around the entire scene. I did that with a timelapse that I shot at Yosemite and it gave it a nice effect, even though the camera was on a tripod the whole time. I'll try to dig it up so you can see what I'm talking about.
You seem to have already figured this out, judging by your video, but keep everything locked down manually (exposure settings, white balance, focus) to make the timelapse easier to process. Even doing this, you'll invariably end up with some degree of flickering at some point. LRTimelapse sells some software to help solve the flickering problem...I've tried it in the past, but I haven't used it for a long time. After Effects can help to smooth out the footage as well by blending frames together...I can't tell if you did this or not, but if your shooting interval ever ends up being too short (things move too much between frames and it looks janky when assembled into a timelapse), this can help to hide that issue.
Here's an example of a recent one that I haven't bothered to deflicker. The camera was locked down completely on manual settings, but variability of the aperture and shutter mechanisms in the camera cause the flickering.
If you want to try your hand at motion timelapse, Monoprice makes an inexpensive panoramic rotating head that you could probably rig up to a linear slider with a rope to get it to pull the camera along the slider. I forget which system uses this design, but there's at least one commercial solution on the market that takes this approach.
As for the timelapse above, I shot that on a 6D with the Rokinon 14mm f/2.8. Settings were ISO 12,800, 20s, f/2.8, and I shot it all in RAW. That clip is 300 frames and I think I assembled it at 24fps?
