Another problem I am having is the lines that make up the clock. They are way too thin and therefore once they are angled are become near invisible. Will have a play around, or more likely, ask the tutors how to fix!

EDIT-
Problem solved, Paul showed me how to make the lines thicker, and now they look proper, even when angled.

Some design problems with the different icons, The lightbulb one hardly looks like a lightbulb from a distance once drawn on flash. I have redone it to look like a generic bulb more and included very cheesy flash lines. Although they are cheesy, they do make the symbol much more recognizable, which is the overall goal of the icon in the first place.
