The show is called Mound Activity vs. Slime Theory. At a guess, I'd say Jonas is the proponent of 'slime theory' and Sarah is undertaking mound activities...but I might be wrong.
Some of Jonas' works...
(this one reminds me of Quentin Blake's illustrations)
...and some of Sarah's.
The two artists' each have a side of the subway; their works face each other in a kind of visual stand-off.
It's a fun exhibition.
It runs until April 30.
