The Betacup entries open for rating for a few more days
The Betacup has closed for submissions, but rating for the entries is still open until June 15. The contest is looking for alternatives to the paper coffee cup because it uses up a lost of energy and resources and most of them get thrown away. Even if you're not concerned about rating, it's fun to check out the ideas that people have come up with.
Also, check out the video below that illustrates the need for a solution.
