Spot UI design flaws with this addictive quiz

Can't Unsee

They say that if you want to ruin someone's life, simply teach them how to spot bad kerning. But if you want to take things a step further, just point them at Can't Unsee.

Can't Unsee is a little online game created by Alex Kotliarskyi that'll draw your attention to all the little details that make up good – and bad – UI design. Each round shows you two similar images of an interface, and all you have to do is decide which design is the most correct. Once you've made your decision, Can't Unsee overlays the images on top of each other so that you can compare the two by switching between them.

Jim McCauley is a writer, performer and cat-wrangler who started writing professionally way back in 1995 on PC Format magazine, and has been covering technology-related subjects ever since, whether it's hardware, software or videogames. A chance call in 2005 led to Jim taking charge of Computer Arts' website and developing an interest in the world of graphic design, and eventually led to a move over to the freshly-launched Creative Bloq in 2012. Jim now works as a freelance writer for sites including Creative Bloq, T3 and PetsRadar, specialising in design, technology, wellness and cats, while doing the occasional pantomime and street performance in Bath and designing posters for a local drama group on the side.
