Acton meet bonus quiz

I have prepared a 7-part bonus quiz for the meet tomorrow, but as not everybody can attend in person the parts will also appear in this thread at the same time they are released (hourly, starting at 3pm). The unmodified version is a giveaway, this will be released at midday on Sunday.

All the parts are online already but are not publicly visible until the time they are due to be released (assuming the technology works, I've had mixed success in the past!). This thread will not show as updated and you may need to refresh the page before you see new parts. If by about 5 past the hour the latest part isn't showing then try and get a message to me at the meet and, if somebody has an ssh-capable device with them, I will log in and release it manually.
