Has anyone else noticed the heavy emphasis that has been put on black holes or black circles in the first couple of episodes??

We have the empty pan on the stove (black circle) before Candle/Halliwax puts the baby's bottle in it to heat up.

Then we have the spinning black record

The holes drilled in the rock under the Orchid - which are zoomed in on and remain on screen for a bit

The black circles on the windows at the funeral home when Jack goes in to see Locke's coffin

All of these were presented in sequence, in the first 5-6 minutes of the premiere...maybe it's just me, but it stuck out like a sore thumb the first time I watched it and even more so the 2nd time. Did anyone else notice this at all?
