Image links broken; now fixed.
Oct 28, 2012 at 14:23 comment added Douglas Zare I wonder what future archaeologists will make of it.
Oct 28, 2012 at 0:04 comment added Mike Hall The model in the picture is unrelated to Falconer's construction except in spirit. It's a back-solution to getting a desired projection on one day, and a solid shadow on others, which is a much simpler problem (and I don't think would satisfy Joseph O'Rourke, but I could be wrong).
Oct 27, 2012 at 23:40 comment added Alexandre Eremenko Here is another link to NASA APOD with the same photo: asterisk.apod.com/viewtopic.php?f=9&t=28968 Here is another link to the Falconer paper: springerlink.com/content/8p231p31k7247p38 But I am afraid you still need a subscription.

Oct 27, 2012 at 23:26 comment added Alexandre Eremenko The second link is broken indeed. It worked yesterday. I hope NASA will fix it soon. For the first link you probably need a subscription for the journal (Intelligencer).
Oct 27, 2012 at 20:10 comment added Alexander Chervov From the first link I also cannot get the paper...
Oct 27, 2012 at 17:58 comment added Alexander Chervov It seems the second link is broken :(
Oct 27, 2012 at 14:37 comment added Alexandre Eremenko I also thought so, until I learned about working models, like the one shown in the photo in my answer:-)

Oct 27, 2012 at 5:28 comment added Mike Hall I would think Falconer's construction is far too complicated to implement in any realistic setting (even with lots of computing power). Lots of splitting into many pieces and recursively modifying each piece.
