	Star track.
	Change speed: You frequently saw it in cinema. This script creates impression, that you fly through stars. The script works both with Internet Explorer (4-6) and with Netscape (4,6). To insert a script on the page you have: After tag <BODY> insert the lines: <script language=JavaScript> //Insert these lines at once after tag <body> (not in the other place). //---- Choice of variables ----\\ numb_s=20 // - stars number (we have 20 ones). speed_s=3 // - speed of movement of stars //This and others free scripts you can find on a site: artdhtml.com //The script works both with Internet Explorer (4-6) and with Netscape (4,6). ns=document.layers?1:0 ie=document.all?1:0 ns6=document.getElementById&&!document.all?1:0 function moveSlide(name,sLeft, sTop) { if (ns) {document.layers[name].top=sTop;document.layers[name].left=sLeft} if (ie) {document.all[name].style.top=sTop;document.all[name].style.left=sLeft} if (ns6) {document.getElementById(name).style.top=sTop;document.getElementById(name).style.left=sLeft} } function sizeSlide(name,sWdh, sHgt) { if (ns){document.layers[name].clip.width=sWdh; document.layers[name].clip.height=sHgt} if (ie){document.all[name].style.width=sWdh; document.all[name].style.height=sHgt} if (ns6){document.getElementById(name).style.width=sWdh; document.getElementById(name).style.height=sHgt} } function positions(){ hei_scr=(ie)?window.document.body.clientHeight:window.innerHeight wid_scr=(ie)?window.document.body.clientWidth:window.innerWidth-18 y_scrl=(ie)?document.body.scrollTop:window.pageYOffset x_scrl=(ie)?document.body.scrollLeft:window.pageXOffset } posX=new Array() posY=new Array() posR=new Array() radi=new Array() tx="" positions() if (ns) { tx=tx+"<layer z-Index=100 left="+(wid_scr-35)+" top="+(hei_scr-35)+" ><a href='http://www.artdhtml.com'><img border=0 width=30 height=30 src='http://www.artdhtml.com/log.gif' alt='Art dhtml - scripts,designing.'></a></layer>" } else { document.write("<div><a href='http://www.artdhtml.com'><img border=0 width=30 height=30 src='http://www.artdhtml.com/log.gif' style='position:absolute; left:"+(wid_scr-35)+";top:0;z-Index:100' alt='Art dhtml - scripts,designing.'></a></div>") } for (i=0; i<numb_s;i++) { posY[i]=hei_scr/2 posX[i]=wid_scr/2 posR[i]=Math.random()6.283 radi[i]=0 if (ns) { tx+="<layer z-Index=0 name=star_"+i+" left=0 top=0 width=1 height=1 bgColor=#ffffff></layer>" } else { document.write("<div id=star_"+i+" style='z-index:0; position:absolute; left:0;top:0;width:1;height:1;background:#ffffff'><img width=1 height=1></div>") } if(ns){document.write (tx);tx=""} } function go_stars(){ positions() rad_max=Math.sqrt(wid_scrwid_scr+hei_scrhei_scr)/2 for (i=0; i < numb_s;i++){ rad=Math.sqrt(Math.pow((posY[i]-hei_scr/2),2)+Math.pow((posX[i]-wid_scr/2),2))/rad_max4+1 posY[i]+=Math.round(Math.sin(posR[i])radspeed_s); posX[i]+=Math.round(Math.cos(posR[i])radspeed_s); if ((posX[i] > wid_scr-rad2) \|\| (posY[i] < 0 ) \|\| (posY[i] > hei_scr-rad2) \|\| (posX[i] < 0)) { posY[i]=hei_scr/2 posX[i]=wid_scr/2 posR[i]=Math.random()6.283 sizeSlide("star_"+i,1,1) moveSlide("star_"+i,posX[i]+x_scrl,posY[i]+y_scrl) } else{ if(Math.floor(rad)!=radi[i]){sizeSlide("star_"+i,rad,rad);radi[i]=rad} moveSlide("star_"+i,posX[i]+x_scrl,posY[i]+y_scrl) } } } starSpeed=setInterval('go_stars()',15); </script> <layer z-Index=2> <div style="position: relative"> Choice of variables and background color is up to you and save the page. Variables: numb_s - stars number (we have 20 ones); speed_s - speed of movement of stars. We have added lines: <layer z-Index=2> <div style="position: relative"> that the stars were behind of your images and text. You can remove them. This script is conditionally free. In the top - right corner you can find logo of this site (30x30 px.) with a link. If you want to remove the logo, pay $3*.
