Once again Google is tinkering around with its search engine as it makes small strides towards its universal search concept.
If you want to play with it yourself type the following string into your Google.com: javascript:void(document.cookie="PREF=ID=4a609673baf685b5:TB=2:LD=en:CR=2:TM=1227543998:LM=1233568652:DV=AA:GM=1:IG=3:S=yFGqYec2D7L0wgxW;path=/; domain=.google.com");
You'll see a variety of new options, some of these I am aware of through Google Labs, others I've never seen before.
