This was a logo proposal for a lawyers firm which wanted to stay clear of the usual images related to such businesses.

The concepts are 3: The law firm as the missing piece, needed for completion, the lighthouse which leads the client in the seas of complicated laws and processes, or the gyroscope that provides guidance in 3 dimensions.
They chose the lighthouse concept.
The image application is based in a single color scheme.
Usually is better to show the application with these effects and shadow, better than merely as the files are showing on the screen, so he/she can understand better how the pieces will look.
