Sometimes it's the simpler designs that hold the most weight. For those of you feeling particularly playful, check out this medieval castle play set designed by a Czech toy-maker. We got the hook up from Lil Snob and they don't seem to know who exactly this designer is either, which we guess makes the set even more charming.  Built in the traditional city of Brno, each piece from the set has been designed to fit together using a straight-forward and simple linking system. Built with small children in mind, the set comes neatly packed in a store away wooden box.    We feel there's something particularly pleasing about making playthings entirely out of wood. Remember the forest xylophone we wrote about awhile back?   Order a medieval castle set for your child (or yourself) here and stay tuned for more from the mysterious Czech designer. We've  heard rumours of extensions for the medieval castle coming soon…
