Health Warning

This game relies on a fast changing dot-pattern to trick the brain into focusing on the depth illusion instead of the pattern breaks that become very very obvious when these pattern breaks start to move. A small percentage of people may experience seizures when exposed to these rapid pattern changes, even with no history of epilepsy or seizures.
Viewing stereograms for extendes periods of time can be very straining on your eyes and brain. Please take regular breaks.
I am no health expert and these warnings are meant as a friendly precaution.

Above is an interactive stereogram. A very basic flappy bird clone. You play it entirely with Spacebar. There is no support for mobile devices.

The game is software-rendered, meaning the CPU is doing all the work. The performance is therefore dependend entirely on your CPU. Since this was made as a proof-of-concept and for me to learn about autostereogram I have currently no plans to do any kind of hardware-acceleration. 16 colors for the pattern are randomly generated on page load. You might get colors that are too similar in hue or brightness. In that case I suggest reloading the page until you get colors with a good contrast. Below are some options to play with and investigate on how they affect the illusion. You might even find settings that work better for you.
