Abstract: An apparatus is disclosed for making complex and beautiful arrays of marbles or other translucent decorative objects in a free creative manner. A base has structure defining a rectangular grid for engaging both marbles and structure for supporting marbles above the level of the base. Such supporting structure includes support posts engageable with the base for holding marbles at their respective upper ends and inclined risers, both free standing and supportable for facilitating inclined displays of marbles. Substantially horizontal elevated platform structures, similar in configuration, but smaller than the grid, may also be employed. Flexible and segmented support posts add variety and interest.
