The Four Become One

I was at a friend's house last night just hanging out enjoying some coffee when I looked above their kitchen table and noticed an almost perfect circle of light above their chandelier-ish style lights. Upon further inspection I noticed that there were four individual lamps arranged around the fixture each covered with a shade. The shade on each of the lamps had a small hole at the top, so not only was the shade directing light back down onto to the table, but it was also allowing a small amount of light to escape out the top. The circle on the ceiling was not perfectly focused, it had soft edges and some chain shadows in it, but overall I thought it pretty impressive that the light made that shape on the ceiling. Without the things that I've been learning in class I probably never would have observed this or paid any attention to the lights in this way.
