User Reviews

Evil Twin ★★★★ by Mark Zoccoli

This app is wicked cool!

Excellent! ★★★★★ by Ascib

The illusion works really well and my kids love it. Well worth a look.

Good fun illusion ★★★★★ 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.
