First, it's not code. It's just a datamatrix that reads "Hello, world!" Second, you would need to do some heavy filtering and distortion to process the image into a square, readable form. Here's a 1-bit PNG processed from an image taken from the programmer's flickr site. It scanned on my G1 just fine: http://bit.ly/4lxG4U http://bit.ly/4lxG4U

Cool PNG! As an update, I'm still trying to get the semacode software to work in OS X, and it's just not cooperating. Sun recently pre-released a J2ME environment for OSX, which is frustratingly buggy... Here's a link to the SDK: http://java.sun.com/javame/downloads/sdk30_mac.jsp http://java.sun.com/javame/downloads/sdk30_mac.jsp ...and here's a link to a thread about the (apparently common) issue I'm having: http://forums.sun.com/thread.jspa?threadID=5412666 http://forums.sun.com/thread.jspa?threadID=5412666 Glad to hear semacode JAR works on cellphones. If you get it working in an emulator, please let us know about it! EDIT: meh, forget it... the Sun SDK just isn't ready for primetime. Instead, I recommend libdmtx: http://www.libdmtx.org http://www.libdmtx.org It's available from macports, there's wrappers for tons of languages (e.g. python), and although it doesn't magically work with your PNG, I think it only requires a little tweaking... EDIT 2: Forget the version from macports... just compile from source, and your PNG works fine using version 0.7.2
