An interesting apparition at Camps Bay

I'll be on vacation next week, and beyond all reason I managed to leave work early to head though to Camps Bay for one of the last gloriously warm summer days of the season. I say "beyond all reason" because for the last few years I've never managed to leave the office earlier than 7pm on the day that my vacation starts.

Anyway, all this is besides the point of this post's title. Isn't that an interesting apparition indeed? Any guesses as to what's happening in the photo?
