Hello Sarah, 

After referring myself to some code, I can say that win32 native display is 
not supported by ImageMagick. So I would have to compile and package 
RMagick with an X windows server. This is not an immediate priority to me, 
since that would bloat the RMagick 'gem' further. 

So no, no Image#display on Win32 systems. 

best regards,
