Although the normal websites have things that are clickable, and so does Zyra's website, there are also a great many selectable links which are in the text, in-line links. This allows for concept-specific things to be mentioned in passing, and then you can follow the links and find out more by visiting examples of the actual content.
Links are clearly highlighted by having them underlined and possibly in a different colour, which is a tradition that's been around since 1996.
Here are a few gratuitous links for you to try...
Baby Pigeons //// TV tube smashing //// Sprinklers //// Airships //// Underwater Lizard
