Loving Marianne Anderson's collection of phone sketches of everyday objects

Sketch paint apps have officially got artistic kudos (thanks Hockney!) with the narrow spectrum of marks available making a simple kit of communicative parts. The results are becoming more and more visible as artists and designers alike share their working process and daily observations in flattened accents and straight-from-the-packet colours.

With not a little charm, Marianne Anderson has been recording just such drawings in regular, side-on and cross-section views of vessels and furniture, no doubt informing her own colourful product design work. Like totemic diagrams, they’re a great-looking set.
