Right now, I'm working on our last big project in my Vis Dev class. It's based on the same short stories of Gary Soto, except this time we each had to some up with a treehouse design that charter in Gary's stories may have created when he was younger.
I decided that my overall theme I wanted to have was "Adventures in The Great Outdoors" which lead me to creating things like a pirate ship shaped tree house and a submarine shaped treehouse. I'm leaning towards my submarine idea, so I think I'll push my future ideations in that direction
Here's a few things I've doodled searching for my idea :)
