first i have measured the dimensions of the n900 then took it to the adobe illustrator and designed it into my MM logo. i used some MDF wood to mill out the design with my own cnc which made few months ago.

then traced and cut the border of the signboard in MDF wood again. In the front i have acrylic where i have carefully placed the milled out logo and glue it in place. then i placed the phone and glued some small pieces of MDF wood around to phone to hold the phone in place. the final step was to add some back light and screw all back together.
