We've gotten a little bent out of shape over gravitational lensing recently (see here and here). But the fun doesn't stop: gravitational lensing has now officially come into the 21st Century with the release of Eli Rykoff's GravLens. (Not to be confused with GRAVLENS, Chuck Keeton's immensely useful and powerful gravitational lensing modeling software). You can now lens a star, a galaxy, or an image of whatever or whomever you want (e.g., your favorite blogger), right in the comfort and safety of your own palm. GravLens is freely available at the iPhone application store. Go download it, and make yourself a beautiful Einstein Ring. This is your chance to support the fledgling "Physics applications for the iPhone" industry!
