It's easy to tell it's a countdown if you had just right clicked on it and clicked to view the image and read the name.
Good find though,
Symbols are a bit more cryptic.
I made them transparent and layered them over each other, just showing the "constellations", trying to see if they combine into some form of symbol but I couldnt see anything good. The first and second "Constellation" seem to layer over each other *slightly*
