Me and my shadow...cactus

I tried to take a photo last evening but the light was just not right - cacti need sunshine!
I have quite a growing collection and they seem very happy on their wall. I think they will be recurring subjects.
One large one in a pot is getting very big flower buds and I am so curious to see what will bloom. Cacti flowers can be rare and dramatic and colourful. And photographable. blipable. :)
