this was mine last spring. it is in flower at the moment. I will try to get a picture tonight, if I remember, but it has had a rough autumn not getting watered & fed whilst I was off my feet, so is only just putting buds on whilst the smaller one has not even considered flowering yet, though it is typically a much later flowerer. But it has grown quite a bit this last year... needs a good wash though to get some of the dust off it.
I actually used to have a real one of these when I was a student... I called it Nobby The Cactus... I made it some cardboard arms and legs (dangling over the side of the pot) and a cardboard top hat covered in tin foil. Probably why I got a 2:2 degree, wasting time
