One of the illusions from Eyetricks
Eye tricks is one of those free apps which I downloaded ages ago and haven’t used much since.
There’s nothing wrong with it but it’s just not that exciting.
It consists of 30 different optical illusions, some animated, some not. The standard is pretty high’ and there are some classics in there, like the “is it a vase or is it 2 faces in profile.
It’s interesting but now that I’ve reviewed it I’ll be deleting it. There’s no real replay value.
