All of the tubes on the this page were either created by me using various tutorials and applications or made by me from my own or public domain images, and are free for your personal and/or commercial use in images. Please do not include these tubes for download on your own tube pages, or offer them for sale or redistribution in any other form. If you think others would enjoy them, please give them a link to this page, not the tubes themselves. A credit or a link back to this site is always appreciated, but is not a requirement for use.
