File type icons

This is a dynamic icon I designed for Proctest – an end-to-end online testing platform. This file type icon generates dynamically according to the required type of file for the respective field. Check out @Darin Dimitroff's original shot to see the actual file upload component.

When the developer specifies the file format the field requires, the system takes the attachment and places it in a text tag inside an SVG icon. The color of the type is randomly selected from a predefined list of shades.
