Thx
The space invader's eyes are just Led, and have no fonction !! But it's a great great idea !!
For the admin buttons, credits, pause and menu i use the monitor's buttons that you can see in the 1st picture like and the power button of the monitor power up the computer.
For the boarder it's actually made with orange tape, cause i really don't know what kind of paint i have to use to have the same result
If anyone can help me with this, you'll make my day
I have 1st try red tape but yes the orange one make it better
Thx anyway
