requesting spoilers for lava and projector rooms

[kcchesnut]

1) Lava room
i managed to trial and error my way through this room, but want to tie up some loose ends.
To the immediate left is a 3x4 grid of symbols, how was I supposed to use that?
On the back of the flowerpot picture is a series of perpendicular lines, what was that for?
To the right, behind the seaside picture is the 2 handles and a clock-like mechanism. I basically just kept flipping those until it triggered, What should the logic have been?
Also got lucky, by putting all the rings in the statue.
Breaking the pot was another happy accident. Basically p&c adventure game reasoning to just try everything.

2) Projector room (with overlapping red marks)
I have no clue on this one.
Ended up having to go to a youtube vid to recreate the pattern.
After seeing the pattern, I'm still at a loss for how to get that.
How was I supposed to figure this out in game?

Other assumptions.
The flower pot with wilting flowers. I'm assuming that a flower died whenever completing a path.I've got one remaining, and think its because i didn't win one of the shogi scenes. If so, don't know how to get back to it.
The carving that gets coins added to it. I'm assuming that marks all possible endings?
The chalice that fills with blood. That seems to be all death scenes. I did solve a few without dying and don't know how to go back.

Thanks

1. All of those elements are connected, but you missed one important element on the ceiling. The lines tell you where to look on the symbol chart. The symbol chart directs you to the markings on the ceiling. The ceiling marks tell you which way to move the clock hands. The vase was complete BS with no logic behind it, though. I tried interacting with it so many times until I accidentally opened an empty draw for a second time.

2. It's the layout of the room. The 4 pillars in the corners, the 3 projectors, and the doors and button at the ends of the room.

3. Flowers and coins are different sets of endings. The blood comes from dying. If you missed any during the prologue (before you get access to the 3 doors), then you have to start the game over to get the achievement. BTW, the shogi games all have different endings depending on whether you win or lose, so you'll have to repeat them to see everything. One of them has multiple endings depending on how many times you win.
