Underware have a limited edition of 100 numbered posters for sale at €80. Six colour silkscreen printing in Pantone and glow in the dark, nice. If you haven’t already worked it out, move your mouse between Day and Night above. The press release on Typophile reports that the poster comes free when you buy the full Underware collection, but I can’t find reference to that as an option on the Underware site itself. I might be missing it though.
