So a few hours ago, as part of the ever-phenomenal Thinking Digital conference, I took part in a demo presentation in which I was hooked up to a headset which allowed me to control things with my mind alone. It’s not every day you get to say that, and it seemed like a good idea to write down some thoughts.

We've been big fans of reCAPTCHA since we first saw it in 2009. By the time Luis von Ahn had finished speaking about it at Thinking Digital in 2010 - receiving a standing ovation from some of the awestruck crowd - we'd vowed to one day feature it on one of our sites. So we're pretty excited to finally be able to feature reCAPTCHA on our blog.

Those of us who use Twitter were pretty animated about Thinking Digital, generating a thriving backchannel via the #tdc hashtag which filtered and refined ideas alongside what was happening onstage.
