Box art available for Linux users?

[Yuhaney]

Well of course the best would be that in a single box, all versions would work so that it won't cost more to sell Windows or Linux version ... all the game data are system independant, and only the executable is linux or windows which makes it easy to provide multi platform on a single CD/DVD.

Remember that there's Mac version as well.

By the way, just an off-topic question:
Is there the 'super_secret.exe' file on the Linux version?
