This is the first installment of the Fortnightly Topic Challenges Rerun described here and the forty-second installment of the FTCs overall, with topics suggested and voted on here. This fortnight's topic is "Wordless Connecting Walls" (suggested by Stiv) and will span from the 1st of November to the 14th of November. During this period, we will compile the list of relevant questions and post it as an answer to this question.
In the meantime, please go and propose and vote on future challenges!
Everyone have fun, and happy puzzling!

Wordless Connecting Walls
A connect-wall puzzle most often involves partitioning 16 words into 4 categories, often with a final connection between the 4 categories too. However, in the past we have seen impressive connecting walls that break this mould, instead using (e.g.) sheet music, cryptic clues, missing vowel puzzles and even computer code!
This challenge would be to create a connect-wall puzzle which breaks the usual mould and presents its 16 connecting components in an interesting or creative alternative way, not simply as 16 individual words.
