How can I tile a sphere using the minimum number of differently shaped units? I have a 3 meter diameter sphere and I need to tile it using units that are each about 400 square cm (ie like a 20 x 20cm square). The units must be flat (ie, not spherical triangles). [more inside]

Digital Comics: I'm looking to download .cbr and .cbx archives of comic books. Not so I can steal the latest X-Men book (though I know piracy is rampant in this sphere), but so I can read interesting and long out of print books on my computer. The Metal Men, for example, fascinate me.

The trouble is, I can't seem to find any repositories of old comics via Google, BitTorrent, etc. I know they're out there - any help?
