Today for my last activity we had to draw an optical illusion. I drew one which looks like a tunnel of some sort and its going down.

You also don't need to buy anything for most of them because most of the time you only need a pencil and paper!
They are really fun to do, it looks very smudged but it looks so trippy and cool to look at once you start to see it! Here is what I made:
