UPDATE: It's been a day, so let's open this up to any interested solvers.

A recent Connect Wall I wrote seemed to attract some interest from newer solvers, so I'm putting together a few of these puzzles to provide a gentler introduction to this puzzle type.

A Connect Wall is a set of sixteen words/proper nouns/phrases which can be broken into four groups of four related items, where the relationship can be described by another word/proper noun/phrase. The four items defining the relations are themselves related, and that relation is defined by a single word/proper noun/phrase as well. Stiv's excellent post provides more information about these puzzles. Good luck!
