Hello,
I'm pretty new to Linux's. I've been slowly learning, and I really enjoy these. I have a speech in class to persuade the class about anything of my choice. I chose to try and convince them that Linux is a much better operating system than either Mac or Windows. I got a lot of data and had a thought that if i were to get an old computer to run very fast it would definitely turn some heads. So I loaded Puppy Linux on it and I want to find a way to make it look like Windows 7 and give the power point on it, then to pull back the podium and show them that I did all of it on a HP6633C computer made for Windows 98. I thought that it would definitely bring my point across. Any advice on how to get the effect I'm looking for?

Last PuppyLinux version is pretty nice, but it doesn't look like Windows 7 though.
Anyway I don't think the essence of free software is really represented for looking like Windows or Mac. Linux can be so much prettier by its own methods and techniques.

Maybe you can make them change their mind by showing them how customizable Linux is.
Here's a guide that explains a bit about the different parts that a Puppy Linux theme consists of.
