I know what you’re thinking, these tees are pretty normal looking, nothing special, not really worthy of blogging, right?

Well, Mister (or Missus) Know-it-all, prepare to eat humble pie, because these tees are heat sensitive. As the temperature rises the cloud begins to fade away and the sun appears, which is not only a really cool use of heat sensitive ink, but also a great way to illustrate the point behind this design.

You know when its winter and the days are really short and it starts to get you down? A more extreme version of that is Seasonal Affective Disorder (S.A.D.), which is what this tee is very cleverly highlighting. As the weather gets sunnier and hotter, your tee is hotter, and therefore gets sunnier, and you’re happier, sooo cool!

There’s another design that has a cloud on it which brings up the message “the sun is nature’s prozac” which is technically just as impressive, but I don’t think it has quite the same impact.

Neither are for sale, unfortunately, I think they’re just part of a designer’s portfolio. [via Kottke]

*The designers website seemed to disappear as I was writing about the tees, so those links probably won’t work, unless there’s just a temporary issue.
