I like this as an example of solving something pretty tricky without a lot of work. The author got good results, based on the Youtube video, by noticing that the dinosaur doesn’t move, and therefore locating the dinosaur is simple, and extended that concept to finding other things.
Not all problems can be solved by such simple means, but when they can, might as well do it.
Appears to be down at the moment.
Use the cache, Luke.
Though, unfortunately, it has images. And, now, it’s back up.
