Affymetrix 5.0 microarray
A microarray that can be used to assay half a million or so variable positions in the human genome.
Now completely outmoded by the 6.0 array, which does over 900,000, plus another 946,000 or so non-variable parts of the genome to boot.
Also shown - the ugly pattern on the guest chairs in my office, somewhat blurred to reduce the strain on your eyes.
