the condition caused by playing too much tetris, where the sufferer sees falling tetris blocks wherever they look.
this effect can be more severe with closed eyes.

other symptoms include:
-craving more tetris. this temptation must be fought at all costs.
-trying to decide which tetris blocks would fit into any space you see
-lack of motivation to do anything other than beat your current tetris record.
one quick game will have me in tetris syndrome for days.
