I decided to create a square one using the largest lazy Susan bearing I could find at Bunnings, together with some 9ml marine ply and a couple of brass piano hinges.
In order for pots to handle the tilt I added a couple of timber edges on the lower sides which seems to work fine. Now I just need to give it a paint with some oil/stain and it is ready to go.
It really didn't take long for anyone thinking of making one.
