Memory Care activity for men with Alzheimer's Disease &/or other dementias. Easily assembled, there is no "wrong" way to put the pieces together. Materials cost under $20 | 1/2" PVC, I bought 5' and cut it into segments of various size to fit in $3 Walmart plastic toolbox. Bought some joints to fit and a rubber mat to keep pieces from rolling off the table. Pieces are just the right size for arthritic hands to grasp.
