Here's an example of light affected by gravity from General Relativity.

In this example we have two women. One is situated in a room with a light and the other is outside the room observing it.

In this image the observer is watching the woman in the room and everything seems normal. There is one light on the wall opposite the woman, casting light into the room and allowing the observer to view the room.

But if the room with the woman was travelling downward at massive speeds because of a downward force (close to light), and this is the point in which the room passes by the observer (not travelling downward). To the woman inside the room, everything in the room appears normal. Light will hit all sides of the room the same as before. But to the observer the light will be curved in the travelling direction. The speed of light is always a constant, so for the woman in the room a photon of light will travel from light source straight across the room, but to the observer that same photon will have to curve as the room moves downward in order to reach that same point in the room.

This shows light being affected by gravity. Although light is the fastest attainable speed and the limit at which information & energy can travel, it is not instantaneous. Because the lightsource is part of the room it is affected by the same directional pull of the room. As the photons from the lightsource travel across the room, according to the observer they will curve as the room travels down, affected by gravity.

Lack of Simultaneity from Special Relativity.

In this example we have two people, one in a car travelling at a fast speed and an observer on the ground.

Here the car is crossing right in front of the observer.

Just as the car is right in front of the observer two bolts of lighting come down and strike near the front and the back of the car, equal distances tfrom where the observer and the person in the car line up.

The speed of light is constant, so the light from the bolts reach the observer at the same time because they travel the same distance. For the observer this event happens at the exact same time. However, for the person in the car the lighting bolt in front appears before the lightning bolt behind the car. The direction of the car shortens the distance the lightning bolt in front needs to travel. For the person in the car the lighting bolt in front existed first.

This shows that time is not a fixed reference frame. Events that appear to be simultaneous to one observer can occur at different times for another observer.

Here are a few images to a recent visit to the Museum of Contemporary Art in Chicago. Although the museum is a bit small there are some great works on display there. A sizable collection of Andy Warhol work was there, a lot of prints (car crashes and movie stars) and videos. Also a large exhibition of Wolfgang Tillmans photography was there, which captured a very contemporary underground party scene, I'm assuming Germany. And some very nice mobiles by Alexander Calder.
