I remember at one point you could have used those mini CD that could hold about 50megs of data or gigs of data. I don't remember which size off the top of my head. Some people used those to create like a virtual webpages that could be loaded into Firefox or Google chrome. Or make something like programs that you had created on your own and give it away without source code. I make mine over here on Word or word processor from Open office. Does the same thing and pick up the business cards blanks from Walmart.
