What is hidden in the red rectangular frame?

It looks like a bunch of pins
In a red rectangular frame
What should I make out of it?
Let me try and play

I press my palm on cold steels
And watch as the shape formed
The shiny thing followed what I gave
I saw my hands transformed

The world mimics what we think
The universe delivers what we order
Let us declare what’s in our hearts
So our dreams will not go wander
