Was it an electric eraser? Looks kind of like a fat marker pen with a small eraser nib that spins. Used for erasing out small fiddly areas without wiping out everything around it.

like one of these: http://www.chromacolour.co.uk/store/animation_eraser_sakura.asp (first one I found on Google, not my recomendation or anything).

The Gurch:

Could it be a pencil line hoover? You know, for sucking up pencil lines.

And what kind of lines have you been sucking up recently, Gurch? I thought it was just the Monet that had gone to your eraserhead. 

Wow, that sounds sucktastic.

Has anyone tried an electric eraser? How is it?

Chews through the rubber though. Good to have, but wouldn't lose sleep over not having one.
