Snappy Touch's Noel Llopis tells Gamasutra, "I'm still very much an independent developer, and I've been working on prototypes for my next game full time for the last few months."
Llopis and Mystery Coconut's Miguel Angel Friginal released Casey's Contraptions, a Rube Goldberg-style puzzler for iPad, to critical acclaim last year. Like Angry Birds (and other popular titles like Crayon Physics and Tiny Wings), it's built on the open-source Box2D physics engine.
In a trailer announcing its latest Angry Birds milestone, Rovio hinted that it's working on a new Casey's Contraptions title, with a redesigned version of the game's titular character, for mobile devices. Llopis and Friginal previously said they were working on an iOS version of Casey's Contraptions, but they've yet to release one.
