Is this based on open research or is the idea of gradients over text itself the patent-pending invention? I'd love to integrate this with my iOS speed-reading app (http://velocireaderapp.com http://velocireaderapp.com). Any interest in collaborating on a spin-off iOS app, to read, say, DRM-free ePubs? My contact info is in my profile.
