@dillyd Jean Dubuffet comes to mind immediately.

@dillyd lovely crazing.

What I wish β€œcrazy” meant.

@ollicle you got me curious about the etymology and it seems like crazy came from crazing.
@dillyd
smooth and superb. i&i love this kind of image.
@dillyd @joybooster oh, that's cool! I can feel how the potter swirled the glaze onto the cup!
@deborahh @joybooster
I take it you do pottery?
@dillyd @joybooster no, just an admirer, but I do make art, so I'm used to looking closely at things. See those swirls, starting in the middle?
@dillyd It's the wormhole at the end of the cider cup! πŸͺ„
@dillyd I love this kind of abstract shot, so well observed! If it was taken this month, would you consider adding 'Zine permission granted' so I can include it for consideration in the e-zine I plan to produce for #MonochromeMarch? See pinned post at the top of my timeline for more info. Thanks, Steven
