157 pieces, July 2011; a similar layout to before, except with
the pairity of the interlocks reversed. I've had to repair it
(about six months later) since the multiple adjacent holes makes for
a weaker shape; the fact that it's Denton's favorite and has been
played with a lot, probably contributed.

193 pieces, October 2011; this sat around unfinished for a long
time, because I was unhappy about managing the six-way intersections
gracefully, and feared that the result was much more difficult than
I had intended. It is indeed quite hard; Denton hasn't been in a
puzzles mood for a while; when I showed it to him, he got as far as
putting together the lighthouse and the area around the anchor, then
he gave up.

26 pieces, December 2011; I had glued up the board for Denton, then abandoned
it when he abruptly outgrew tray puzzles. George (at 26 months) can solve it easily.

130 pieces, January 2012; the layout here is hexagons, paired, with the interlocks all placed in the same direction for each hexagon - so all the pieces, other than edges, are approximately the same shape. It has the oddity that the edge pieces can be sorted (to which edge each belongs to) by the direction of the interlocks. It's quite hard to solve, despite the easy subject matter.
