This article gives credit where it's due and even critiques its efficiency since offices probably won't end up using the pencils all that much in the long run...... however they totally fail in seeing the BIG picture:
(-L) + ink = pen... a biodegradable pen, which, if I'm not mistaken, would actually be the best idea to hit the water-cooler in quite some time (there are already mainstream bio-pens but this would be right in the work space, keeping shit localized). Also plenty of professions use pencils: artist, architects, accountants, mathematicians, landscape designers, fashion designers.. the list goes on. I'm not sure how this isn't already happening everywhere. I love this idea and I want one.
