What, who, where am I?!?
Craig Lotter is a web developer based in Gordon's Bay, South Africa, who seems completely incapable of shaking off that pesky inner child within, the one that forces him to love all things animated or hand drawn.

jQuery: Invert a Selection of Checked Checkboxes
If you have a group of checkboxes on a page, sometimes it is quite nice to give the user some quickfire controls that allows him to select all or select none at a click of a button.
