Puzzle #144: That's So Random (Aleatory Freestyle)

Trying something a little different with this week's freestyle (pdf, puz, pdf solution). Starting with a blank grid, I used a random number generator to choose five squares which had to be black squares, then also randomly chose five white squares and randomly chose letters which had to go in those squares - then I built a freestyle around those preselected squares, following the normal rules of crosswords. The result was a 60-worder with a weird pattern that I never would have come up with on my own. (In the applet below, the preselected black squares are in gray, and the preselected letters are in green.) A fun exercise, which I encourage other constructors to try out!
