As fun as Snapchat's augmented reality World Lenses can be, there are only so many times you can see a headphone-toting hot dog before you crave something new. Wouldn't it be nice if you could make your own? Well, you can: Snap has unveiled a Lens Studio tool that lets anyone on Mac or Windows create their own AR effects for use in Snapchat. You do need some experience in 3D object creation, but you're otherwise off to the races -- you can submit your masterpiece and give others a Snapcode to unlock it. Those codes only last for 24 hours, unfortunately. However, you can share codes again if you like, and recipients can share them with others and spread the word.
