Today I reconnected an old hard drive that contained time machine backups for an old install. I decided to make an aged version of the Time Machine drive icon so it could still be easily identified as time machine, but also remain easily distinguishable from the current disk. While I was at it, I made a companion icon for the second partition on the disk.
So far I've only made these two. If there's enough interest I'll make a few more, so comment below and let me know what you think!
