Hi starwolf,
we do not necessarily need a new siduction logo, but the artwork should be based on the design of the logo, redesigned (developed). This begins with a single wallpaper for Grub boot manager, possibly a simple splash screen for the boot process, the design of the login manager, the splash screen of your desktop environment and the wallpaper for your desktop. This list is certainly not yet completely around the artwork of siduction to improve completely ;-)
If you have suggestions and ideas are welcome.
The implementation of the artwork must then of course be coordinated with the siduction team.
