Advertising by jigsaw puzzle

I had a task to create smth for advertising on a touch screen which has a face regonition and be placed in a hall of building, near lift.

So, I used idea of jigsaw puzzle, which can be skiped, if a person wants to see a menu of touch screen application. Pictures are chosen by a system taking into account person's interests which are said in persons's profile in mobile app. After finishing puzzle person will get special promocode on discount in mobile app, which is synchronized with mobile app.

I tried to fullfill two main goals - 1. to show advertising, 2. to give smth for passing the time while waiting for the lift
