Abstract. A 3D Computer Graphical tool was developed for creating "Kolam" patterns of the southern India or Celtic knot patterns in Europe on digitalization of them. The 3D CG pattern consists of six primitive stroke patterns on the six sides of a block (called as PsyKolo3D). A user is able to change the patterns with rotating each block in an array to create a single stroke pattern as a cycle on a "smooth" tracing rule excluding acute angle curves. This software checks automatically if the pattern is a cycle (unicursal). This interactive content was designed for anyone including a child and the aged to operate naturally for enjoying it and activating his/her brain.
