I've been caught in that part of the web where the spider pounces and binds you in silk. Until I regain normal color, here is something you don't see often: a massive webcomic crossover involving numerous strips: The Mighty Tubularman, Failed Objective, Bitmap World, Apple of Discord and Maskerman.
By the way, if you are involved in a cameo or crossover project, the management of the Webcomic Cameo and Crossover Archive likes to hear about it, and they are always friendly and appreciative.
