Thank you Mockingbird, there were only a few images on Professor Google but I can see the similarities. The purple in those cactus' is beautiful! I agree with you - there is something very beautiful about cacti and succulents. I inherited a unique little succulent when a colleague left the firm I work in and every day I admired it, and the little changes that happened each day aaand I fell in love, or into addiction, with plants and am now building quite a collection.
Make it your goal, do it, do it, do it - peer pressure.
Document your way through it - I would love to see the growth 'journey' from a baby purple octopus into a mumma of a purple octopus..
