Almost has the look of a Dracaena reflexa about it but not seen one this colour.

I think it is probably Tradescantia spathacea 'Tricolor'

Checked that, Fractal, not that one, but I did find it on the same site - its Tradescantia bermudensis variegatam apparently. Same site suggests that some plants previously classifed under Zebrina are now Tradescantia, is that true?

I think they are synonymous with each other?

Botanical Name: Tradescantia bermudensis ‘Variegata’ or Tradescantia spathacea ‘Hawaiian Dwarf’ (synonym: Rhoeo bermudensis variegata, Rhoeo spathacea nana variegata)

I thinkyou're right - but they used to be different plants grouped under Zebrina or Tradescantia - I must say I'm finding it difficult to keep up with all these nomenclature changes, they seem to be very frequent these days - or perhaps its that telescoping time thing that happens as I get older...;-)
