phpaintings: painting number 1: Microsoft stock quotes

[Lemmy Caution]

Yes, it looks MUCH like the previous experiment I did with dynamically generated images(it should, seeing as how it's built on the previous experiment's code); this one, however, relies on external data to decide how many (randomly-placed)solid lines, dashed lines, and randomly-colored pixels to use. The external data is generated from Yahoo stock quotes for Microsoft stock...

This is great - I wonder if you couldn't extend it to an actual aesthetics
of painting, i.e. other shapes, line thickness, etc., the kinds of things
you find in vb? A whole art could be built around this! - Alan

[Deere Warener Nard,]

Or is it a wry question about delimited semantics?
What is a painting? What is paint; when the very 'substance'
of 'art' has become an abstraction (and abstraction a form
or specie code?).. By connecting chromatic
variation to the manifold of informatics by linguistically privileging
the culturally recognizable limits of a 'frame' within a narrowly
functioning aleatorics, the piece seems to point to both
art's limited role in society as well as the individual's limited
understanding of the process behind any 'object', but that very
limitation is coextensive with its possibility, ie infinite limitation=
infinite possibility which says to me 'extremely human'
ie paradoxical to say the least..
