Those who take a close look at the recently launched Xbox Virtual Museum will find a lot of interesting stuff. In particular, the museum has an “exhibit” dedicated to early interface concepts for the first Xbox.
Microsoft is showing in a museum two versions of the first Xbox’s interfaces that were ultimately not used in the final version of the console.
The first option is called FROG. You can see his work at video here… You can see some screenshots below.
The second option is called BLUR. You can see his work at video here… Below are some screenshots.
Note that the same Xbox Museum has published logo options that were considered possible for the first Microsoft console.
