I recently purchased myself an iPhone and Macbook Pro to begin development for iPhone applications on the side. Learning Objective-C has been a bit weird, but easy at the same time. I can only do very basic things for now, but even then, I'm beginning to see how everything will come together. Hopefully I'll be able to get through several of these books by the end of next week and really get started. I've even joined several iPhone developer meetup groups in hopes to learn more about creating applications for the hardware. I guess I'll post some art I've done randomly when showing people how to use Mudbox.
