The DIY inclined might wish to round up three Ikea Lack coffee tables (Craig’s List). Cut them in half and mount as shown for the “dominoes,” with raw edges facing the floor. You could then either find a suitable glass top, or use the Lacks’ shelves to create a table top.
Perhaps not as lovely as the finished pieces from Sidd, but some bargain hunting would probably get you close for under $60.
Although the price tag might seem a bit ambitious, when you consider the fact that it’s made completely by hand, and to spec, from sustainable local hardwood, it’s completely within reason. In fact, in an area where many ‘green’ designer companies are taking undue advantage, SIDD seems to have both feet on the ground.
