Another interesting property of the logarithmic spiral is revealed if you roll it along a horizontal line. This animation shows the curves traced by points on the spiral, and note that the very centre follows the path of a straight line. The angle between this line and the horizontal is called the pitch of the spiral, and for our spiral galaxy the pitch is around 12 degrees. [more] [code]
Sunnyvale, CA-based artist Hoang Tran (previously featured here) continues to create so many awesome pop culture-based crayon sculptures that we can’t help but share some more. Last time we featured crayon sculptures of Adventure Time characters. Today we’re treated to carved and painted pieces from Doctor Who, Spirited away, Star Wars, Hellboy, The Sandman, and sweet little BMO (who was still a work in progress last time).
Visit Hoang’s Tumblr site, Wax Nostalgic, to check out many more crayon sculptures. He also has some available for purchase via his Etsy shop, CarvedCrayons.
