[High Praise! to Pixactly via Neatorama]
Pixactly is both a game and a quiz that tests your knowledge of graphic space in pixels. You are challenged to draw a box of specified pixel size, both horizontally and vertically. The game keeps track of how many pixels you are off over five attempts.
I got 205, but I cut 150×110 and 75×75 images every day in my day job.
Let me know how you do.
I got 137, and that was just by gut feeling. (my horizontals were pretty exact, off by only about 5-7 pixels consistently, but the verticals were off by a bit more)
I got 400. I had, and have, no idea what the native pixel density is of my 24″ LED monitor. When I work in pixels, it’s part of my photo hobby using Photoshop, etc. and my pix are never set at native display sizes.
820. Dang!
