Tinkering with pixel-pushing on the phone.

Pixels: An almost comically unambitious project: takes an image, and updates it
pixel-by-pixel using the Von Neumann (nearest neighbor) neighborhood. Canonical example: Conway's Game of Life.

LuaPixels: Same as above, but the pixel transformation rule is applied through user-input Lua code. Currently gets about 4s/frame on the phone on the Game of Life.

Subversion client for iPhone OS 3.0

This is an example Xcode project that implements a simple NSCoding-compliant Model class named CountdownTimer.

The executable product is a simple View-based iPhone app that shows four timers. The timers are automatically unarchived when the app loads and are archived when the app terminates.

This is a fork of the original Chatty sample app by Peter Bakhyryev. Chatty is "a simple chat application for the iPhone. It allows you to host your own chat room and advertise it on your local Wi-Fi network (in which case your app acts as a chat “server”) or find and join chat rooms hosted by other people on your network (acting as a chat “client”). Both announcement and discovery of chat rooms are implemented using Apple’s Bonjour protocol. The goal of this app is to show you how to use various networking-related frameworks available in the iPhone SDK version 2.x. The UI is minimal (consisting of only 3 simple views) - just enough to be able to play with the core functionality of the app without having to deal with complex UIKit code."

This fork is by Jens Alfke. It replaces the networking code in Chatty with my MYNetwork library, a general-purpose networking framework that provides Bonjour service discovery, client and server TCP streams, and a powerful messaging protocol called BLIP.
