For those who don't subscribe to the main mailing list, there has been movement on better support for icons. Stephan Assmus has come up with a way that should allow vector icon support in R1. He also has written a new version of Icon-O-Matic to support the format. Read about it here:

A new set of icons will be needed for Haiku. Stephan has provided format specifications for these icons. To help develop guidelines for these icons, a basic design contest is being set up. The current expected end date for this is September 1, 2006. Read about it here:

As stated, he is currently expecting links to be posted to the mailing list. PM me (Katisu) if you need me to do it for you. If there is enough submissions, a web site will hopefully be set up.

Please don't be afraid to experiment and submit multiple designs, this contest is mainly to come up with ideas and guidelines for the final designs.
