Progress goes slow when working with old computers and having limited access and time to use said computer. But, I have been making headway on an old game design of mine! In preparation, I’ve been making some new Optical Illusions and studying up on them too. Without further ado, I present to you a couple backgrounds I’ve been working on for the game and a little background info!
Zöllner and Contrast
Based off of a tileable Zöllner Illusion I made (following Picture).
I decided to use contrasting shades of black/grey/white to get an almost 3D effect and induced motion in this picture. Although a bit hard to tell if the original Zöllner effect is still at play, I do really enjoy it. Moving towards and away from this picture causes such drastic stretching/expansion along the lines for me but seems to diminish the maze creation effect the following picture seems to have for me.
Another Zöllner Illusion inspired picture that seems to exhibit some interesting phenomenon… I personally find that if I am look at it up close, the fringe areas tend to look more like a maze than the H pattern stair set I see at the center of my vision. This might be due to the shades of grey I chose to use for the image, but is a neat feature nonetheless!
A simple checkerboard that appears to be twisted based off the inverted outline and “knots” at the corner. While making some of the other Optical Squares I went down to the basics for this one to see what effect the knot was contributing. As you will see in the following Optical Squares, this is a base illusion that contributes to the overall activity of some of the others.
Grey Square with Scintillation Blurs
Like a hybrid between a bent line illusion and a scintillating grid, this pattern really is something I’m proud of. I was running into an issue where I didn’t like how the “knots” appeared when the line going through the squares intersected, it created a great broken line effect but doesn’t seem quite right. I decided to put these scintillating points there instead to see how it went and I was happy with the result.
Grey Square Alternate
As mentioned before, something doesn’t sit right with me about the “knots” at the corner with the diagonal but I have to admit I find the lines do some awfully funny things in this one. I decided to share it anyways as it’s still has illusionary properties and merit.
Optical Squares #1
Based off of a picture I made in 2009, this version of Optical Squares is fairly randomly placed except near the center. Although it might not be the strongest example, it still has a bit of line bending and distortion.
Optical Squares #2
I decided to add a new primitive to the mix and create the corner piece to experiment with. In this example I created two opposing spirals, which seems to create a pit to me, but others may perceive it differently.
Optical Squares #3
My next experiment was to use complimentary spirals and I do believe the effect is stronger with this version.
Optical Squares #4
I also tried a mix of spiral and concentric squares and found it to also be a useful mix. It seems like wen I look at it in my peripherals that it still has the concave I noticed in the earlier ones but is quickly dismissed when looking directly at it. Once again, could be a subjective thing as I made it…
Optical Squares #5
Finally I made a version with both having concentric square patterns embedded. I find the line bending seems a bit more accentuated to myself than previous iterations without knots but once again, that could be subjective and as the creator I have doubt in my own vision after staring at these pictures over the past few days.
Original Square Illusion (2009)
This is my original square illusion from 2009, and upon looking at it again I wonder if my new versions would benefit from fatter lines… Something for me to consider I guess…
Maybe not as spectacular as some of the others, but I find it’s a nice, quick example of how border color affects our perception of a contained color. Only using black, white and 2 shades of grey here.
Cube Conflict with a Charlie Brown Stripe
Although not a solid Charlie Brown Stripe like on his shirt, I found it a reasonable description of the zig-zag that isn’t typical in these types of cube conflict… I find it adds an additional layer of impossible object to the cube conflict when I start seeing the upside down dark topped cubes touching the right side up slightly less dark topped cubes. If that makes sense?
Rectangular Prism Conflict
What can I say, I messed up making the pattern and made some stubby cubes but found it to be quite an enjoyable pattern anyways…
Cube Conflict (for reals!)
I cheated… just used resize on the rectangular prism conflict to make a more cubic conflict…
Sideways Cube Conflict
I like it better this way, kinda forces people to perceive it wrong no matter what…
Nothing really new here, just an old dog in a new hat… there’s many examples of how our brains misperceive the brightness of things and this is no different. All squares are the same yet from top right to bottom left it appears to get darker…
Bending the Lines
Although not a pixel perfect diagonal (a double pixel up every 118 or so pixels) it sure appears to be more wavy on the secondary lines than it is. A very rudimentary illusion and only a small, quick example I made… was making something else and it was just easy to make along the way.
Cyan Magenta Checkerboard-Ish
This might not even be an illusion, but I find it really looks like a checkerboard pattern from a distance without my glasses (or while squinting for all you 20/20 and farsighted people). I also find there to be a really strong 3D element if you look at the pattern like one of the old MagicEye 3D pictures.
An old mockup screen of my game concept (WIP)
A bit hard to tell what’s going on here, but I figured some explanation is better than none… I’ve been slowly working away at making a puzzle platformer based around optical illusions. Nothing to share yet, but hopefully soonish…
