The Cross Lap Unit (CLU) consists of a long strip into which a number of notches have been folded. These notches can be placed on either edge of the strip, and matching notches from two units, or different notches from a single unit which was bent, allows connections to be made. Especially the option of making a single long unit, bending it into a complex shape, and connecting the ends, opens up many interesting possibilities. The name comes from a similar device used in woodworking.
