Sony recently released a
tool that goes along with the 2.00 firmware for the PS3, allowing users to
create and set themes. Despite the original application being written in Python (you can see that by not passing any arguments to the application, and seeing that they forgot to check for the length of the ARGV before trying to poke at it), the converter to their home-grown image format (GIM) isn't written in that language. A
wine install and a couple of
DLLs later, I can run the tool on the sample theme.
It's been
done before on the PSP. So here's my take on the Tango icon theme for the PS3:

Kudos to the Tango artists for their nice looking icons, and particularly Jakub who provided me with some icons that weren't readily available. Sources are
here. It's still missing a few icons, can't say the theme format is well documented...
