Daily UI 013 - Direct Messaging

For Daily UI #013 - Direct Messaging - I've always loved the visual thesaurus bubble interface, so I wanted to mirror that with a brainstorm chat app. I've only scratched the surface here- but my thinking is someone would throw an idea out there (the largest bubble) and then folks would comment off of it, and as you comment on other's comments it would provide context with the content, but be presented in a different way than linear like we're used to.
