Nice aren't they? I intentionally chose different appearances and styles for them to illustrate a tiny portion of what is possible. There are other styles, horizonal, LCDs, well, you can look for yourself. The really cool thing is you can experiment with the look and type right on the screen to get what you want. Yes, these are (almost) real time. I update every minute, so if you wait long enough, they'll change. The little blue and red ticks on them represent the high and low for the last day. Think about what they would look like with a weather station.
Then, later when you change your mind, go back to GroveStreams dashboard and change them. Since the way they embed them is to use the dashboard object, all the places you've used them change as well.
Slick, really slick.
