Shadow / Spider icon
The font at the top is "console 8x8", and at the bottom "Invite SF". I was going to change it, but the name seemed appropriate :) Behind "parlour" it says "Shadows" in the Shadow font. The words themselves come from a verse - "Come into my parlour, said the spider to the fly". The (probably invisible) spiderweb in the background comes from a picture by crumblingwalls.
The font on this icon is called "Prisoner SF". The border, again, comes from crumblingwalls. The words are more-or-less a Biblical quote; I felt they fit the way Lyta ended up in Season 5, searching for the Promised Land.
