I have colored the menu buttons in my own way. See the pics below for before and after. You can still grab these files from in the IRC chan if you want to replace the menu buttons. Until the menu buttons are finalized, these are restricted to IRC at the moment. For those who still don't know how to get to the channel here's the info:
I worked on getting new menu buttons made for Beast and this is what it turned out to be (see the pic). All the menu buttons, hopefully, have been replaced. They look rather nice at the moment but hopefully they'll look better when they're colored. Beast said himself that he'll be doing the coloring.
If anyone else wants to step in and help with these menu buttons, come in the IRC channel and I'll send you the links to the files. These are currently private at the moment and won't be given out on any forums. You can still grab these even if you don't want to help. Having new graphics over the old OA ones are so much better.
Please keep in mind these were created for use of Beast's PAK8 file. They should look just fine under normal OA circumstances.
PK3 can be located at the bottom on the attachments of this post.
