It occurred to me that if accretion is the noun for a thing increased by layers then accreting should surely be the verb that describes the process. And it is.
So I can say with confidence that I have been accreting today. Indeed, accreting in 3 dimensions.
The general impetus is that I want something quirky and eye catching to hang outside the shop. Something durable, weatherproof and pretty.
It could take many, many forms but I am beginning with this sphere. Layer one almost complete.
