More ways to get Braingle...

Unstable Fins

An optical illusion is a visually perceived image that is deceptive or misleading.

 

Puzzle ID:#28639
Fun:*** (2.77)
Category:Optical-Illusion
Submitted By:JakeAadminus*mod!!!

 

 

 



Are the points marked with A and B in front, or in back? There are no depth cues, so its impossible to tell. As a result, the image becomes unstable and may appear to flip from front to back as you continue to look at it.

this is so confusing. we definately need more of these. get our minds going.
Freezinjoeus*
Aug 28, 2007

it looks to me like it depends on which side you start looking at first is where the A and B will appear.Focus on where the 5 lines intersect on left and they appear in back. Focus on the 5 lines on the right and they appear in front. But for me if i focus on the right first it is hard to adjust when i focus on the left. Could be just me though
luckylefty*is*

A looks like it's in front
Akatsuki_NekoAus*
Dec 03, 2007

Same with Freezinjoe. Kinda looks like they intersect... also makes your brain hurt a bit...

i dont think this one was very tricky... 'a' and 'b' are both in the back. it says there are no depth clues, however there really is. if 'a' and 'b' were in front, then how does it make sense for the back two fins to be larger than the front? depth perceptions tell us the further away an object is, the smaller it will be. based on that assupmtion, then clearly 'a' and 'b' both are on the back fins.

Whooaaa... I could stare at that all day...
emily103**
Jan 20, 2008

A and B could be in the front because they could just be smaller than the back fins. There's no rule saying that isn't possible. (If you're thinking it wouldn't balance, maybe it's hanging by a string.)
I look at these a lot and now I can switch which fins are in front at will... Great optical illusions!

Ack! >.< Makes me feel jittery when those fins flip sides.. kinda eerie. Thanks for posting!

Since the AB fins are smaller than the oter ones, I see them in the back cause of perspectives.
