I just completed my latest creation. Instead of carving out a design on a Xbox 360 I decided to carve on a laptop and the best computer for the job was a Dell D630. The back is painted a dark blue and it has etched vinyl on the Plexiglas inside.
Right now I am currently working on a second laptop that will be fixing some problems with the prototype. The 2nd one will have the cutie mark shifted downwards because there is a problem with it being so high, and it will be painted a lighter blue color. Also the cutie mark will illuminate from the LCD panel. It should be completed by the end of this week or the middle of next week.
If you have any questions please ask.
Thanks to ~Psyxofthoros for the awesome background
