Gradients are the love of my life, and I adore this idea. We can totally make this work. Would you like it to have an overall red theme for Wanda or would you prefer other colors?

As far as the details moving out from the side, I've made a plurk layout like that before. Let me know if this movement is similar to what you were thinking.

And as for transparent plurks, I usually only make the muted plurks slightly transparent to kind of hide them. Would you like me to not add that?
