Typography has become increasingly interesting to me this summer. Hence I'm developing an uppercase typeface. I've been experimenting with the golden ratio; The height devided by the width of every letter (except for the letter O) is equal to phi. Within many letters you will find the golden ratio as well. There's still a lot of work to do before it can be used as a font, but it'll be worth it!
Urethane floor covering, used to protect the floor from office chair scratches, maintains its shape when it is deformed and heated. That's what I discovered when I got rid of some rubbish, resulting in a suprisingly flexible chair.
