To make sure I get your assignments in a way that I can run without problems, you need to follow the following guidelines when delivering an assignment:

• First give your sketch an appropriate name from inside Processing. The name should contain the code of the assignment and your full name. An example would be “EX03_MariusWatz”.
• Make sure all external data files (images, .vlw fonts etc.) are in the sketch, and that you can run it normally.
• If you use a non-standard library (i.e. Minim etc.), please include a copy of the library in your sketch folder.
• Use the “Show sketch folder” menu selection to find the sketch folder in your operating system. Use a ZIP or RAR archive application (WinRAR, Stuffit or similar) to make an archive of your sketch folder,
  giving the archive the same name as your sketch (i.e. “EX03_MariusWatz.zip”).
• Email it to me at marius at unlekker net.

You should always post at least a few screenshots of the assignment on Flickr.
