Bjarne Jespersen is a danish artist who primarily works with wood. His interlocking, and intricate sculptures are skillfully constructed because they are carved from a single piece of material. In addition to building his wooden sculptures, he has studied the many different configurations of polylinks. Alan Holden found and constructed a fair amount of the various polylinks however, Jespersen found and built the ones that Holden had missed and donated them to Smith to complete the collection.
