One logo... I thought of this name and the style of the logo with the two Ds in my sleep last night.
I've drawn some graphics for the user interface too, which has an industrial look and feel, but I'm finding it difficult to marry together the neon and industrial themes for some reason.
The neon logo looks so clean and airy and futurist, while industrial textures look grungey and solid and old in contrast to them.
I like my game logo. It seems to invite using wire frame graphics somewhere in the GUI, either for icons or some sort of 3D wireframe models in the title screen.
In one of my previous games I managed to combine these two themes very successfully, so I may have to look back on that.
