make

I want to make an encoder that puts the alphabet backwards like so: abcdefghijklmnopqrstuvwxyz zyxwvutsrqponmlkjihgfedcba so that the letter on the top encodes to the letter on the bottom. I don't know if this is possible but any response will be very helpful. If I need to be more exact just...

I have made heaps of web browsers, Text Editors, and a couple of picture viewers, and i am getting better each time i make one:), finding better code, pictures, and tricks, but i am getting bored of makeing these... Any ideas of other things i could make? Thanks, Haxaro
