Beautiful Bitmaps is a recent project from Uppercase Magazine:
For issue 15, we invited 26 typographers, designers and illustrators to make beautiful bitmaps by taking this vestigial part of digital type—the bitmap—and making it into something to be newly appreciated.
Each letter is available in print form at Society 6. A portion of the proceeds wil go towards an UPPERCASE scholarship fund that will assist a reader in pursuing education in design, illustration, typography or craft.
Thanks for the tip, Dominique!
