These irregular, sculptural blocks from New York-based Brinca Dada are hand-carved from teak hardwood. According to Brinca Dada founder and CEO Doug Rollins, the blocks aren’t meant to be used in just one way but are “a puzzle with infinite solutions.” What I like, is that this means the set will still work even if you lose a piece or two (which happens constantly with small kids). Better yet, it’s not something that kids (or parents) will get bored with easily. Ideal for aspiring architects and artists of all ages, the sets are available at the Brinca Dada site for $59.00 USD.
