if you want to experience it for yourself
set the ground plane texture to bricks
run this in console:
function servercmdjoy(%cl, %c){if(!%cl.isAdmin) return; groundplane.loopsPerUnit = %c; groundPlane.sendUpdate(); %m=2/%c; %cl.player.setScale(%m SPC %m SPC %m);}
/joy .4 to scale it correctly for a "5 5 5" scaled player
/joy 10 to scale it correctly for a ".2 .2 .2" scaled player.
/joy 2 to return it to normal.
credits to buddy for giving me this code
note: this will only create persistent player bodies if you really screw something up
