I think it's safe to say that the Auxo jailbreak tweak was a resounding success. As you may remember, it initially started out as a concept posted on The Verge forums. Its designer, Sentry, hooked up with a more than capable developer, and eventually the pair made the concept into a successfully reality.
Well it appears that Sentry is back, this time with a new concept aimed around improving the functionality of Apple's built in Do Not Disturb feature. While Apple may not think that it needs improvement, judging from the advertisement spot it just released showcasing the feature, Sentry believes that he can improve Do Not Disturb by meshing it with Notification Center.
