Varying "tech talks" based on time of day

I'll be speaking at DDD South West later this month.

I'm one of the last sessions of the day. It's a slot I've not had before.

In general, if talking at part of a larger event, I try to include something to link back to earlier talks in the day. Unless I'm first, obviously.

At the end of a day of talks, where most attendees will have already heard five other talks that day, I'm wondering about including something to draw together threads from the earlier sessions and provide a conclusion that also ties in with what I'm talking about. I have a few ideas...

I've seen someone do a wonderful job of this before but it's not something I've ever heard mentioned in advice to (or books on) presenting... I guess if you'll there you'll see what I do.
