Leni's hubby hated it aesthetically - but got very excited (as I am too!) about all the physics and chemistry and mechanics of it.
It's awash with colours - reds, blues, browns, ochres, greens, purples - it's got every effect of silver chloride salts imaginable - and it's got effects from the use of tin as well - they're the grey-ish-black-ish matt-ish metal spots.
It does have a big burst bubble in it - but thankfully, it's not in a place where it detracts in any way from the thing.
(It just made it slightly less unaffordable, for which I am grateful.)
