Kinda like being on mushrooms.

The green/purple dot thing was insane. I had to watch it twice to make sure the dots disappearing and the colour change to green wasn't actually in the animation.

An idea that just struck me. The information contained in the aforementioned sequence is simply a finite amount of dots of one colour while one dot changes to the same colour as the background at a time, (essentially zero). The information of the dot changing colour to green and the others disappearing is decoded by the human brain. Could these kind of tricks ever be used as a form of information compression?

Not so impressive as those are the absolute standard illusions you can find on thousands of sites across the internet.

Meh. I've seen all of these before... The last one I even saw (on the intertubes) back in the late 90s...

Seen them all before, many times, but still an upvote as I do love an optical illusion... although the text was terrible, someone loves their exclamation marks a little too much!! !!!!

But I do like Enigma, so upvote for the music

Ironic - with the exception of the initial demonstration of top-down processing in text comprehension, none of those have much to do with the human 'mind'. They are mostly functions of subcortical structures, primarily the retina, and some processing in the lateral geniculate nucleus (part of the thalamus). [edit] Motion detection is definitely associated with area V5 of the occipital cortex, but the data has been heavily processed by that point. The neurons in V5 are almost certainly activated by the motion illusions, but the illusion itself is caused by the wiring of the retina and LGN.

As for the text demonstration, it's worth noting that your ability to read text like that is severely hampered, though not completely degraded. This has be shown by reaction time studies of all sorts. There are even neural network models that have been developed to demonstrate exactly that effect. Still pretty neat, though.

You want fascinating - try figuring out how your brain matches up the color of those dots with the shape of them, despite the fact that the information travels in two completely separate neural pathways. It's a low-level variation of the 'binding problem' and is one of the central issues in cognitive neuroscience. Figure that out and you should pack your bags for a trip to Stockholm.

I really hate the jumbled word thing. Yes, it is legible, but it does take extra work. This of course doesn't really matter, but a lot of people use it as an excuse for why spelling is irrelevant.
