> Why is the bottom-right corner of the box not filled in? Because there are only 60 x 60 x 24 = 86400 seconds in a day, but the big box is 300 x 300 = 90000 dots. So 3600 are blank.(4%) Thanks to a reader for the question. ??? Alright... no. 86400 / 9 = 9600 Not quite a square, but it would look better... I guess... though why would I want it grouped into 9 anyway? There may be some reason, but I can't figure out why not 60 dots * 60 dots * 24 boxes arranged in a 6x4 grid. :( EDIT: Oh, it's supposed to represent graph paper. I'm in my mid 30s and that completely went over my head. Just saying. EDIT 2: I also wouldn't expect highly composite numbers to align very well with decimal grids. Such is life. Ah yes... "metric". :)
