If time went backwards, what would you see?

If you were traveling backwards through time, what would you see? How would your other perceptions interact with this world?
Let's say you're a mad scientist & you invent a time machine, only instead of sending you back in time, you reversed the flow of time so that you were now traveling backwards through time - people walk backwards, water flows upwards and... light peals out of the void, bounces off the walls, and gets sucked up by the lightbulb. You're traveling back with a 1:1 ratio to normal time so there's no red/blue shift. What would you see? What would you hear?
For example a red rubber ball. a) what color is the ball? does it have a faint glow as it gives off light? what spectrum of light does it give off? b) if you threw the ball at the wall, what would happen? c) when the ball hit the wall, what would you hear? d) If you put the ball in the fridge, would you put it in cold & have it come out warm? What would the cold air of the fridge feel like to you?
Bonus points: How would other people perceive you? (other than your going backwards, how would your skin tone etc. be affected?)

This post was deleted for the following reason: This seems pretty irretrievably in chatfilter territory. If you have what you except would be a concretely answerable physics question at the core of this that you want to ask, maybe rework this and try again next week. -- cortex
