JS1K is a website which hosts some competitions to attract geeks from the world to create  JS apps which are less than 1K (1024 bytes). The object of this competition is to create a cool JavaScript "application" no larger than 1k. Starting out as a joke, the first version ended with a serious amount of submissions, prizes and quality.

Recently, I revised a previous project of mine and compressed it to 1018 bytes and submitted it. It is an analog clock. The code is shown below:

w=c.width;h=c.height;x=w/2;y=h/2;r=60;o=window;function D(){M=Math;p=M.PI;W="#FFF";n=new Date();h=n.getHours()%12;m=n.getMinutes();s=n.getSeconds();d=n.getDate();a.arc(x,y,r,0,2*p,false);a.stroke();z=a.createLinearGradient(x-r,y-r,x+r,y+r);z.addColorStop(0,W);z.addColorStop(1,"#DDF");a.fillStyle=z;a.fill();a.fillStyle="#000";a.fillText(12,x-7,y-42);a.fillText(3,x+42,y+4);a.fillText(6,x-3,y+48);a.fillText(9,x-48,y+4);for(i=0;i<60;i++){g=i*p/30;B=M.sin(g);C=M.cos(g);a.beginPath();a.moveTo(x+53*B,y-53*C);a.lineTo(x+59*B,y-59*C);a.strokeStyle="GREY";a.stroke();}a.rect(x+20,y-5,16,10);a.stroke();a.fillText(d,x+22,y+4);N=m*60+s;S=p*(h*3600+N)/21600;j=M.sin(S);k=M.cos(S);a.beginPath();a.moveTo(x-12*j,y+12*k);a.lineTo(x+28*j,y-28*k);a.stroke();U=p*N/1800;l=M.sin(U);n=M.cos(U);a.moveTo(x-20*l,y+20*n);a.lineTo(x+40*l,y-40*n);a.stroke();V=p*s/30;u=M.sin(V);v=M.cos(V);a.beginPath();a.moveTo(x-14*u,y+14*v);a.lineTo(x+46*u,y-46*v);a.lineWidth=2;a.strokeStyle="red";a.stroke();a.closePath();setTimeout("D()",1000);}D();
