<noscriptor something like that…
At best you could design a non-JS fallback.
– Obviously, slider doesn’t work in poor browsers like Opera Mini and the Nokia 5800 Browser 7.0.
– Consider making the Slide 2 comment text editable (perhaps CSS3 content after?… not sure of compatibility tho.) and make it unselectable, because it gets selected accidentally and interferes with the sliding action. (I added -webkit-user-select: none;)
Otherwise, cheers, great idea!
