a) is there a huge difference between the summerboard and winterboard? b) this is just kind of an idea, but im pretty sure its not possible.. BUT; what if you could change the slide to unlock, but not design. like, you change the direction you slide/touch to make it unlock. so, you open the app that allows you to do so, and you can do it in stages. lets pretend you want to make it so its a smiley face. so you click step one, then place the left eye, then second step; right eye, then a smile for the third step. OR, you could just do stripes across the screen, or a zig zag going top to bottom. is that possible at all?
