Thanks to a few comments (mainly from Guy) I tightened up the design of the Portcullis logo.
Below are the four iterations I went through. The differences between the first and the second are fairly easy to spot, but a prize goes to the first person (Guy excluded) who can point out all the changes since version 2. (And the darker blue in the fourth version doesn’t count, that’s just me being crap at specifying GIF palettes)
