I thought, for sure he had to be using glue or something to make these things. Not according to this line from his About page -

"I can build freestanding structures out of cards (no tape, no glue, no tricks)"

And he has a few pictures of him knocking down some card buildings. I still find it hard to believe there's no glue for some of these... But Wow! Impressive stuff.

Some of them look like semi permanent exhibits in a large space, surely those ones must be glued? The wind from people walking around would blow them over otherwise, no?

There's some videos on this on the site, where he also blows the structures apart with a wind machine at the end of an exhibition, and topples the towers he built by running into them.

How can I find those videos?

I see he often places multiple cards flat against each other - probably gives the structure more weight against random gusts and jostles.

The last client is Loctite and he discusses the use of glue in that project as the first exception to “no glue”.

If you click on the main images there is a narrative description for each project where he says some of them do use glue - the Holiday Inn one for example.
