Just to show off: I finished my first target for this year!
And an important target, because it's a present for the birthday of our twins next week (they'll be 3 then).
And this is totally off-topic, so you may stop reading now.
But, actually it's also a puzzle. A simple one as you can see: only 10 parts, made from 35 pieces of wood. Placed in the correct way, it's a castle to play with. And it can be stored in a more compact way.
Our boy and girl already were very happy seeing the castle on the computer screen (while engineering it) -not knowing I'd make it for real for them-, and also were very anxious to see some parts already stored in a room and while varnishing it.
So I guess they also will be very happy to actually play with it soon.When interested: the construction manual will become available here
Update 16/04/2012: the manual how to scroll saw and build this nice and sturdy castle is now available via above link.
