there was thought about opening a window in a private thought cloud. an individual could nearly visualize what was going one outside. perhaps there was a moment where one would just ponder what was required in order to express that that as a thought bubble ( with ' softened edges, hence kinda looks like a bubble ' ) might be a bit different.

for now, there is just a strange instance where a simple thought was instigated, and that is where the expression of clouds and bubbles will possibly lead us into the moment where a vision of flying convection ovens was an idea that was investigated for a while.
