⚡️ No costumes ⚡️ Arrow keys If you liked this, please take a look at some of my other projects :) - Pen rendered 3D sphere - https://scratch.mit.edu/projects/94312530/ - Rag Doll Physics (also pen rendered) - https://scratch.mit.edu/projects/92759204/ Some cool optical illusions rendered (drawn) using only the pen blocks. No costumes are used. :) This took a long time to make so if you thought this project was good, please leave a ♥ and ★ to show your support! If you thought this was great, I'd hugely appreciate a follow so you can see more projects like this and to show your support :) Arrow keys for the next illusion. I have never had a featured project so if you like this please request it to be featured here - https://scratch.mit.edu/discuss/topic/2733/ ;) Many thanks to @DadOfMrLog for his tri-fill and pen ARGB blocks. H̲o̲w̲ ̲t̲h̲e̲ ̲i̲l̲l̲u̲s̲i̲o̲n̲s̲ ̲w̲o̲r̲k̲ Squares A and B illusions - The squares look different colours but are in fact the same (press space to make it clearer). This works because the darker colours around square B make it look lighter. Static Ebbinghaus - The centre circles are the same size. This works on the same principal as above - the bigger circles around the circle on the left make it look bigger, and vice verse. Invisible circle - Stare at the red dot the the blue circle will *disappear*. This works by your eyes having blind spots and as everywhere else is white, your brain thinks that the space where the circle is must be white as well. The result? The circle disappears. Penrose triangle - This is an impossible object to make in 3D. It looks realistic but you simply couldn't build it in real life. Unless you look at certain shapes at certain angles of course. Or use Photoshop. Bar with shaded back ground - This is simply a shaded back ground with an also seemingly shaded rectangle on top of it. However, the rectangle in fact just one colour and just seems shaded because of the shaded rectangle behind it. Duck illusion - You blur your eyes and the ducks' heads seem to bob back and forth, when in fact they are simply moving at a constant speed across a series of black and white bars. Dynamic Ebbinghaus - This works on the same principal as the normal, still Ebbinghaus, but with a much greater effect. The circle in the middle seems to be growing and then shrinking again. However, it is actually staying the same size and it is all just an illusion. The favorite-this-project-illusion - This will amaze you. If you click the star and the heart images under the project, they will magically seem to change colour. And if you go the 's profile page and click the follow button, that will magically seem to change too. ;) ╱╱┏╮ ╱╱┃┃ ▉━╯┗━╮ ▉┈┈┈┈┃ ▉╮┈┈┈┃ ╱╰━━━╯ Test - title changed to FIFA 18 Pack Opener Unblocked 2018.2.12 from Pen Projects - Optical Illusions 100% Pen, 410 favs, 505 loves, 3338 views changed back 2018.2.15 at 411,505,3340
