Blue Tree Software is now closed

Blue Tree Software, my shareware “company” that I have had for many many years is now closed. If you visited you will be redirected to

I plan on releasing my flagship product, WallChanger, as open source. The applications all run on Windows, and I only use MacOS, so it might take a while for me to post the source somewhere and rebuild a “freeware” version. If someone wants to build it for me and remove the reg code stuff, let me know…I’ll send it to you.

Before “Blue Tree Software” I called “Blue Software” (even older! Cool main font):

The fruity rainbow design when I was learning Adobe Illustrator and playing with dynamic javascript stuff. Back in 1997/1998ish (and around for quite a few years):

    Hi Corbin,
    I really like your site and comments. It looks like you’re into some interesting stuff. I’m a do-it-yourselfer/restorer also.
    I’ve been using the WallChanger software for a number of years now and was just looking for an update. I see you’ve given it up. Well, sorry it wasn’t more successful for you. I really like it and still use it.
    Good luck to you!
    Fredericksburg, VA.
