We first heard about Letterboxd a year or so ago at Brooklyn Beta. The site has built a solid user base ever since, and has just left the initial invite only model and opened its doors to the public. In doing so, however, the problem of automated signups by unsavoury robots and their ilk started to raise its ugly head.
The solution is elegant, and above all, perfectly judged considering the purpose of the site: instead of unscrambling some illegible letters, Letterboxd asks you to complete a quote from a well known film. That’s an exemplar of how design solutions should be tackled, with great wit and true consideration for the reason you’re there in the first place. Delightful work.
