1. ## Show Off Your LaTeX Skills

Post here any cool LaTeX things you've discovered over the years.

Example:

$\setlength{\unitlength}{.5cm}\begin{picture}(10,10 )\put(2,2){\line(0,2){2}}\put(2,6){\line(0,2){2}}\ put(2,8){\line(2,0){2}}\put(6,8){\line(2,0){2}}\pu t(2,2){\line(2,0){2}}\put(6,2){\line(2,0){2}}\put( 8,2){\line(0,2){2}}\put(8,6){\line(0,2){2}}\put(0, 4){\line(2,0){2}}\put(0,4){\line(0,2){2}}\put(0,6) {\line(2,0){2}}\put(4,8){\line(0,2){2}}\put(4,10){ \line(2,0){2}}\put(6,8){\line(0,2){2}}\put(8,4){\l ine(2,0){2}}\put(10,4){\line(0,2){2}}\put(8,6){\li ne(2,0){2}}\put(4,0){\line(0,2){2}}\put(4,0){\line (2,0){2}}\put(6,0){\line(0,2){2}}\qbezier(0,6)(0,1 0)(4,10)\qbezier(6,10)(10,10)(10,6)\qbezier(10,4)( 10,0)(6,0)\qbezier(4,0)(0,0)(0,4)\qbezier(2,2)(5,5 )(2,8)\qbezier(2,8)(5,5)(8,8)\qbezier(8,8)(5,5)(8, 2)\qbezier(8,2)(5,5)(2,2)\qbezier(3.5,5)(3.5,6.5)( 5,6.5)\qbezier(5,6.5)(6.5,6.5)(6.5,5)\qbezier(6.5, 5)(6.5,3.5)(5,3.5)\qbezier(5,3.5)(3.5,3.5)(3.5,5)\ end{picture}$

2. $\boxed{\bullet\boxed{\bullet\boxed{\bullet\boxed{\ bullet\boxed{\bullet\boxed{\bullet\boxed{\bullet\b oxed{\bullet\boxed{\bullet\boxed{\bullet\boxed{\bu llet\boxed{\bullet\boxed{\bullet\boxed{\bullet\box ed{\bullet\boxed{\bullet\boxed{\bullet\boxed{\bull et\boxed{\bullet\boxed{\bullet\boxed{\bullet\boxed {\bullet\boxed{\bullet\boxed{\bullet\boxed{\bullet \boxed{\bullet\boxed{\bullet\boxed{\bullet\boxed{\ bullet\boxed{\bullet\boxed{\bullet\boxed{\bullet\b oxed{\bullet}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}$
Beat that, Drexel! Don't ask me what it's, though. It's the Penrose staircase inverted for all I know...
Or an optical illusion that gives you the impression that the dots are shrinking when they in fact aren't?

$\boxed{\boxed{\overset{\boxed{\bullet\boxed{\boxed {\boxed{\bullet\boxed{\bullet\boxed{\bullet\boxed{ \bullet\boxed{\boxed{\bullet}\boxed{\bullet\boxed{ \bullet}}}}}}}\bullet\boxed{\bullet\boxed{\bullet\ boxed{\bullet\boxed{\boxed{\bullet}\boxed{\bullet\ boxed{\bullet}}}}}}}\bullet\boxed{\bullet\boxed{\b oxed{\bullet\boxed{\bullet\boxed{\bullet\boxed{\bu llet\boxed{\boxed{\bullet}\boxed{\bullet\boxed{\bu llet}}}}}}}\bullet\boxed{\boxed{\bullet}\boxed{\bu llet\boxed{\bullet}}}}}}}}{\boxed{\bullet\boxed{\b oxed{\boxed{\bullet\boxed{\bullet\boxed{\bullet\bo xed{\bullet\boxed{\boxed{\bullet}\boxed{\bullet\bo xed{\bullet}}}}}}}\bullet\boxed{\bullet\boxed{\bul let\boxed{\bullet\boxed{\boxed{\bullet}\boxed{\bul let\boxed{\bullet}}}}}}}\bullet\boxed{\bullet\boxe d{\boxed{\bullet\boxed{\bullet\boxed{\bullet\boxed {\bullet\boxed{\boxed{\bullet}\boxed{\bullet\boxed {\bullet}}}}}}}\bullet\boxed{\boxed{\bullet}\boxed {\bullet\boxed{\bullet}}}}}}}}}}$

It's a new game called... not sure what to call it, to be honest.

Ok, you got me! That last one was fake. Worth a try, anyway. I actually tried to make it, but it didn't quite work out.
Could someone try it? Not the colour (as it's not enabled in the forum), but the shape I mean. It would be hard, I suppose.

\subset & \sqsupset \\ [-2.7mm]
\supset & \sqsubset \\ [-2.7mm]
\subset & \sqsupset \\ [-2.7mm]
\supset & \sqsubset \\
\end{array}$

Looks like a view of a skewed Mayan pyramid with a cannonball on each step
while holding the reigns of a parachute.

5. want me yo show my latex skills? ah well, i attach here a PDF that i'm currently doing.

it's in spanish.

i got another ones, like geometry pictures, etc.
