Can You Tell What It Is Yet?

Weather awful today - was outside for only a couple of minutes. Wasn't sure where my inspiration for today's blip would come from. Then saw this - it sits on my dressing table. It's like a large paperweight but actually is part of a relaxation machine which sends coloured lights through this and you can add relaxation oils and it has sounds of rainfall and lapping waves. Yes one of those machine that one thinks one needs and then it sits and gathers dust! Anyway I thought it might look interesting in close-up.
