Very ODD 5/5 stars by MrPloppy
My wife is officially freaked out now. This is a simple but very effective app. The results will make you laugh and scare the kids. :)

Evil Twin 4/5 stars by Mark Zoccoli
This app is wicked cool!

Excellent! 5/5 stars by Ascib
The illusion works really well and my kids love it. Well worth a look.

Good fun illusion 5/5 stars by alemaster
Interesting illusion giving an insight into the way our brains visualise and recognise facial features. You can get some fun weird pictures of yourself through the iPhone camera, or start with a photo of someone else for some amusing results.

Waste of money

Don't Buy DOSEN'T Work!

Waste of 2 dollars! It doesnt even recognize touch input. Don't buy unless it's updated.

Was hoping this would work because I like to do this effect in Photoshop and this would save me so much time.
