This may be similiar to what Mr Simpson is referring too, the poormans turntable ( or the lazy man who can't be bothered making one
), I buy them for 3.99 au at an el cheapo shop near me, I put them under all of my large bonsai that I have trouble moving around so I can rotate them to check the rear and give the dark side a turn in the lime light, I believe there intended use is for computer monitors, but on the packet is a picture of a bonsai so I guess there onto the fact that some people use them for bonsai too.
