The top button on most of the menus takes you to the top of the page. I did suggest having links at the end of each page, but Predator (my friend who owns the site) wasn't keen on the idea. Just tap "Home" or something.
The reason that the content isn't in a holding box is because the site needs to be able to resize itself to any resolution - and also because the site was built up bit-by-bit as I learnt new methods and skills. For example, the splash graphic is about six months older than the rest of the site!
And my "creations" weren't actually meant to be used as wallpapers, except for Infraction and Insomnia - they were experiments with filters, so please don't judge them.
Thanks for the input!
