  We propose a versatile optical ring lattice suitable for trapping cold and
quantum degenerate atomic samples at discrete angular positions. We demonstrate
the realisation of intensity patterns generated from Laguerre-Gauss ($\exp(i
\ell\theta)$) modes with different $\ell$ indices. The ring lattice can have
either intensity maxima or minima, suitable for trapping in red or blue detuned
light, and it can be rotated by introducing a frequency shift between the
Laguerre Gauss modes. The potential wells can be joined to form a uniform ring
trap, making it ideal for studying persistent currents and the Mott insulator
transition in a ring geometry.
