ASCII art "Hello-World!"

JavaScript, 178 bytes

c=document.createElement("canvas").getContext("2d");c.fillText("Hello-World!",0,7);d=c.getImageData(1,0,56,7).data;s="";for(i=3;i<1568;i+=4){s+=d[i]?"#":" ";s+=(i+1)%224?"":"\n"}

That works in Firefox 27 Scratchpad.

Mathematica 101 99 98

This rasterizes the expression, obtains the binary image data, converts each 1 to "#", each 0 to "" (empty space) and displays output in a 12 by 130 character grid.

GraphicsGrid[ImageData@ImageResize[Binarize@Rasterize@Style["Hello-World!",99],130] 
  /.{1→"",0→"#"}]

One character economized thanks to Jonathan Van Matre.
