These blocks are cut into a pattern that allows you to make an unlimited number of fun balancing sculptures from the 7 pieces.  Putting them back together in a rectangle is a puzzle with the wood grain as your clue.  I have received numerous pictures of these blocks stacked into beautiful sculptures since I first started selling them in 2016, including videos of kinetic sculptures rocking back and forth.  The two shown in home are by Tom Manning.

Made from salvaged solid hardwood, most of the block sets I have in stock are walnut, which is the darker wood in the picture.  I also have some light ones in maple and ash.  No cherry ones (the reddish wood in some of the pictures) are currently available.  US lower 48 shipping is $15 regardless of quantity ordered.  Email me for your order.
