too good.
u/username

Rubik's Cubes cannot move the middle layer
u/pavel

If you hold the sides the middle moves, no? How could it not!
u/pavel

Here are notation-only moves for(c.width|=f=g=>(k%16&&1+k%2*.414)*g(a=.7854*(k+y*2/(1+1e3**(t%1*4-i)))),k=57;i=--k>>4;x.fillRect(960+700*X/z-s,540+700*Y/z-s,s*=2,s))[X,Y,Z]=[y=i-2,X=f(C),f(S),y,X].slice(t%3),z=3+Z,s=99/z/z
u/username

Technically you are moving both sides at the same time in that case instead of moving the middle layer.
u/katkip

^
u/pavel

That's not what technically means. You have a mental model that only permits sides to move, and you have that model because adding middle rotations would be notationally redundant in that model. This does not mean middle rotations are somehow impossible or that they definitely consists of two side rotations.
u/username

Erm, the middle layer is attached to the core, that is what I mean. It is about the construction of a Rubik's Cube.
u/username

http://www.madehow.com/images/hpm_0000_0007_…
u/pavel

Still seems like this is a matter of perspective. You are chosing a perspective in which the core is always fixed, even though the motion I am describing specifically involves holding the two sides fixed and rotating the core... In my reference frame the core is rotating. So what if the core contains more parts than the side pieces when you take the cube apart?
u/13thptr

that escalated quickly
u/donbright

maybe they dont actually move like this... but they should!

u/Purpzie

Shaved 10 characters but it's super laggy: for(c.width|=0,i=572;Y=(0|i/13)*27,X=(572-i)%13,i--;x.stroke())x.lineTo(X*160+(X&1?C(2*t+Y/108)*120:0)*(X&2?1:-1),Y-(X&1?108:0))
u/Purpzie

Less laggy version that's 4 characters shorter instead of 10: for(c.width|=0,Y=1188;x.moveTo(0,Y),Y-=27;x.stroke())for(X=0;X++<13;)x.lineTo(X*160+(X&1?C(2*t+Y/108)*120:0)*(X&2?1:-1),Y-(X&1?108:0))
