in the browser, javascript's REPL is essentially the address bar. you can type in javascript:alert(2+2) to output 4, or javascript:void(code) just to run an expression and swallow the output. to evaluate expressions more complex than a one liner you can inline a function, javascript:alert((function(){var x = 2; return x+x;})()). that's how bookmarklets work.

For a more psychadelic version, try this: javascript:R=0; x1=.1; y1=.05; x2=.25; y2=.24; x3=1.6; y3=.24; x4=300; y4=200; x5=300; y5=200; DI=document.images; DIL=DI.length; function A(){for(i=0; i-DIL; i++){DIS=DI[ i ].style; DIS.position='absolute'; DIS.left=Math.sin(Rx1+ix2+x3)x4+x5; DIS.top=Math.cos(Ry1+iy2+y3)y4+y5}R++}setInterval('A()',5); void(0); (in address bar)

  the auto-formatting swallowed the multiplication symbols. the actual code should be this, with "TIMES" replaced by the multiplication symbol. is there any way to escape them? javascript: R=0; x1=.1; y1=.05; x2=.25; y2=.24; x3=1.6; y3=.24; x4=300; y4=200; x5=300; y5=200; DI=document.images; DIL=DI.length; function A(){for(i=0; i-DIL; i++){DIS=DI[ i ].style; DIS.position='absolute'; DIS.left=Math.sin(R TIMES x1+i TIMES x2+x3) TIMES x4+x5; DIS.top=Math.cos(R TIMES y1+i TIMES y2+y3) TIMES y4+y5}R++};setInterval('A()',5); void(0);
