Heeeey! Seems optical illusions are popular again! That made me look up some old e-mails for uncopyrighted optical illusions – nothing mentioned at least.
So here they are
What’s up and what’s down?
If you stare at any one point you will notice that they stop moving – same below
Which central circle is bigger?
They are of the same size!
Flashing grey dots!
Do you have a dirty mind?
An innocent mind would see 9 dolphins!
Circle or spiral?
Focus on the cross below.
At first you should see each pink dot turn green in turn.
Then each pink dot will disappear leaving only a moving green dot.
Keep focusing on the cross at all times.
Let me know what you think!
If you’ve got more optical illusions post your links as comments.
