Homages....
I noted quite a few homages to "Blade Runner":
1) The boiling eggs
2) The turtle on its back, in the sand (from Leon's Vioght-Comp test)
"The tortoise lays on its back, its belly baking in the hot sun, beating its legs trying to turn itself over. But it can't. Not with out your help. But you're not helping."
3) I haven't gone back to look at Blade Runner, but I would swear the movements of the police car in its first appearance were made to mimic the flying cruiser's moves in BR.
4) And the more obvious ones: Giant floating balloons, "holographic" projections, the desolation, the rain, the tears in rain, etc...
Anyone got anything else?
