Spatial Challenges - What challenge are you wrestling with? Are you dealing with one now or have one on the horizon? If you're working it now, we'd love to hear your approach. If you're still trying to work out how to approach it, then perhaps the group can offer suggestions.
If you want to bring slides or not, then that's fine. If you don't have something to discuss, I'm sure one of the topics will spark your interest.
See you there!
