And of course, at some of these, you know, huge, you know, booths that we see in the big sort of international events, you know, you can you can monitor people's movement within your own with your own booth, you know, presumably by triangulating sort of positional data between various different sensors that might be in one booth.

Yeah, well, we don't triangulate, but we do pick up that data and tell them where they were engaged and what sensors they were on.

So it's pretty accurate.

We give ourselves sort of a leeway of 10%, but most of the time we're on the money.

People talk about, oh, it was a busy booth.

Well, how busy was it? They talk about, oh, we had lots of people staying here for a long time.

It's anecdotal data.

They'd seen somebody on a booth opposite who basically just had one of these badge scanners, was literally just going for the numbers, trying to mow down as many badges as they could possibly get in a Rambo style over two or three days, however long this event was.

What was that project?

Oh, that was a really interesting one, and it was part of a bigger team.

I was, um...

There were twenty-six scientists involved in all.

Uh, back in about, uh, when was it? Oh, nineteen ninety, there was a man by the...

a scientist by the name of John Martin, and he, the, he had a hypothesis that the large areas of ocean, which were actually quite lowly, they weren't very high in production, even though all of the nutrients were high.

So a lot of, um, particularly tropical areas, large open areas of the ocean, there's lots of nutrients, nitrogen and phosphorus and things to make the plant plankton grow, but it doesn't.

You've also made a, um, a big contrib- uh, contribution to aquaculture, big discovery in Cook Strait, I understand.
