Hey @adamltyson, I'll work on finalising the card images today and on updating the behaviour info.

I designed the missing images for the cards and made sure that they are all of uniform size and style.
This is how they look now (feedback is welcome):

The ephys traces were simulated in Python as Poisson spike trains + some gaussian noise. I didn't bother to model refractory periods though 🤫

I think this can be merged now. I've removed the collaborations section for now, and opened #76 to track adding this.

The various pages now are fairly inhomogeneous, so I think we just need #75 to be addressed, then it's good to go for now.

Looks good! 👍

My only comment was about the consistency of links on each project page. The old project pages had green links underneath while the new ones don't. However, I see that it's going to be resolved by #80.
