11 or 12 depending on how you define a 'pass', but im pretty sure this was looped pretty hard too.

**moose** · Nov6-05, 11:57 AM

I saw 15 or 16....... Sometimes when they pass each other it's nearly impossible to tell if they threw it back and forth to one another or not.

I saw 15 too, I have no clue how cronxeh is getting 11 or 12, but I also don't see how this is an optical illusion, so maybe that 11 or 12 is part of it.

I counted 14, but it was a little hard to tell sometimes when other people were blocking the view. What's with the person in the gorilla suit showing up in the middle?

Is that supposed to distract us from counting?

**mattmns** · Nov6-05, 12:05 PM

Yeah I don't know what is up with the gorilla either

I remember the first time I counted I did not even notice the gorilla go by, maybe that was the illusion?

**moose** · Nov6-05, 12:07 PM

I didn't see a gorilla O.O

**mattmns** · Nov6-05, 12:16 PM

Yeah the gorilla must be the illusion.

I just watched it again, BWAHAHAHAHAHA How could I not see that before?

**Moonbear** · Nov6-05, 12:34 PM

Oh, I missed a pass the first time I watched...there was a really quick one in there. I revise my answer to 15.

Yeah, I'm not sure if the gorilla is the illusion that you are supposed to miss seeing the gorilla while intensely counting, or if the illusion is that the gorilla is supposed to distract you from counting so you miss counting some passes.

The illusion is trying to figure out the illusion

I think there is a deeper social meaning here. We, as humans, just sit around and do stupid things like counting how many times a team passes a ball, while gorillas are out there slowly taking over the world!!!! We must stop these gorillas now!!!

I've seen a verion of this before in which a load of people wandered around in circles passing a breifcase, and half way through someone in a bee costume came to join them. I completely missed it then, but since this time I expected it, it was impossible to not see it.

WHITE team not both teams - watch carefully, there are 11 passes

**big man** · Nov6-05, 12:53 PM

Nah come on, how the hell did you get 11? Can there be that few?

I'd have to go for the 14 there for sure.

I'd bet my left nut that it's 14

I definitely counted 15 from the white team. I was worried I might miss some being passed by the black team to someone on the white team since I was focusing on the white team, but as far as I can tell, the black team never passes to the white team.
