The Lab

Experiments rather than tools. Nothing here has a job to do. These exist because they are worth trying, and because the answers turn out to be more interesting than the rules of thumb everyone repeats.

• Five rounds · about a minuteThe Compression TestTwo versions of the same picture. One is compressed. Five rounds, getting harder, until you cannot tell.
• Five rounds · about a minuteThe Color Memory TestA color appears for three seconds, then vanishes. Mix it back from memory. Nobody is as good at this as they think.
• Bring a pile of photosPhoto MosaicOne photo, rebuilt out of all your others. Zoom in and every tile is a picture you took.
• Pick a photo and a sizePicture PuzzleYour own photo, cut up and jumbled. Tap two pieces to trade them. Put it back in as few swaps as you can.
• Bring a photo · a minute or twoSpot the DifferenceThe old game, except the picture is yours and the changes are made on the spot, so nobody has played this one before, including us.
• Nothing to upload · endlessOdd One OutOne square is not like the others. Every level shrinks the difference and grows the grid, until your eye gives out. No photo needed.
• Bring a photo · press the buttonThe Glitch MachineNot a glitch filter. Real damage to the file, a different wreck every press. Keep the ones that come out beautiful.
• Once a day · about a minuteThe Daily ColorFive colors, the same five for everyone today. Remember them, mix them back, compare with friends. A new set every midnight.
