Underwater lava cave #perspective

Show more comments…
u/tomxor

I keep switching perception between cave and mountain top, it gets stuck on mountain top... i can't control it 😳
u/sigveseb

I don't see mountain top 🤔 how?!
u/tomxor

funny, i can't see anything else now... it;s like looking down from above a mountain peak. Maybe imagine you are looking down from a circling helicopter.
u/rodrigo.siqueira

This #illusion is called "bistable perception". When I posted it was looking like a cave, now it seems to keep changing between mountain top and cave. I prefer a cave.
u/sigveseb

yes, I see it now!
u/rodrigo.siqueira

#tunnel
u/joeytwiddle

To see the mountaintop, maybe look at the blue and imagine it is the floor or the sea, far away.
