I would put webpages in with billboards. Web pages work well as a catalog for art available elsewhere, but the pure art webpages I have found have been underwhelming at best. Prove me wrong, I dare you. I really beg of you, I would love to be proved wrong on this. I can only conclude they damage our sight.
Books are different.
I can lie on the couch and read a book, take it to the kitchen and set it on the counter while I poke my head in the fridge, and sit on the toilet reading it. Besides, the refresh rate on paper kicks ass over the best monitor ever made and glare is only an issue at the beach. As an experiment, I dare you to read the latest potboiler on a computer screen while the Fort Lauderdale sun beats down on your head. All this is a roundabout way of saying that there must be more than text on a website. There must be graphics, there must be color, there must be a coherent visual style.
