Nice one, thanks!

Correct. Probably not needed as the axis force pushes the ants away from the centre anyway.

I've only dabbled with the crowd nodes, but I was able to get a simple setup along the lines you described.
An agent terrain projection is meant to stick crowd characters or particles to a surface, works fairly well.
For orienting the cards that'll have the ant pic, you want 2 vectors, the normal of the surface they're walking on, and the direction they're facing. The terrain projection node provides the first, and the built in @v (velocity) provides the second. Copying the first vector to @N gives the copy to points sop what it needs to fix the cards.
The other things in the setup are nice-to-haves; I tried to make slightly more interesting motion of the particles with a few forces. An axis force pushes the ants away from the start point, a wind adds noise, and 2 interact forces do opposite things; one is a wide soft force to make the ants try and follow each other (sort of), and the other pushes them apart if they get too close.
