Now that you're in the right 'mode' for playing Tetris with no immediate discomfort, it's time to look at where exactly you're playing, and whether it might be necessary to relocate.
Finding suitable lighting is quite a challenge to the avid Tetris player. One must select an area where light is plentiful, yet does not noticably glare the screen. Generally the plastic face is very reflective, and optimally will reflect your own shadow, causing no glare. However, ambient light must be present to actually illuminate the screen. Try out various forms of light and see for yourself.
Your traditional desk lamp. Light emanating from these bulbs generally does not distribute well, and can glare most unpleasantly. If you insist on using lamps, I recommend frosted white bulbs - those used for general reading. Perhaps the lamp itself could be frosted, like a pendant lamp.
It's not the best, but it works astonishingly well in producing full bodied light. Office environments are great for the Gameboy.
Desk lamps will generally produce only glare - highly unrecommended. However, standing halogen lamps that first bounce light off the room's walls work very well. My lamp of choice.
Who can argue with good ol' Mother Nature? I've found that sunlight is probably the best around; great for road trips, hammocks, beaches, even indoors if the time of day is right. Best of all, it's free.
Sucky. Maybe if you're doing 2-player with your romantic partner (along with a bottle of clamato juice or something), it might clinch the 'mood' you're establishing, but still it's pretty sucky.
Ech. Possibly vomit inducing.
So you have this great Gameboy, a great posture, and a great lighting system. Now, where should you play Tetris?
- School.
Not recommended. Could get confiscated by irritated teachers, or 'borrowed' by classmates and never returned. - College.
Highly recommended. - Work.
If you're one of those powerful corporate types, then your cubicle is probably pretty quiet; only the hum of nearby computers and keyboard tapping would distract you. Tetris might fit well here. If you're, like, an air traffic controller, Tetris ain't no good. - Libraries.
Why would you want to play Tetris when there are all those great books lying around? But if there are nice skylights and it's well air-conditioned, then the temptation is probably too strong. - Movie Theaters.
Crank up the volume on your Gameboy and 'spice' up the soundtrack for everyone around you! - Cars.
If you're not prone to motion-sickness, a car can become your best friend. If you're parked, keep the windows rolled down - it'll prevent suffocation, not to mention hearing loss if you scream at your Gameboy too much. - Planes.
Planes would be the best place for Tetris if only most commercial airlines had special Russian music stations (in place of the usual adult contemporary garbage.) - McDonalds.
If you don't mind the grease, you might find a perfect Sunday to be a pile of 39 cent cheeseburgers, a Gameboy, and a bunch of extra AA batteries. - Baseball games.
Highly recommended. - Significant Others' Homes.
Impudently playing Tetris by yourself can be a pretty effective way of annoying your boy/girlfriend if you're annoyed at them. Otherwise, see candlelight (above). - Jury Duty Waiting Rooms.
The ultimate environment. Features some (but not too much) noise, comfy chairs, and the sheer knowing that a) you're still fulfilling your civic responsibilities, and b) you have absolutely nothing better to do at the moment.
