For those of us who enjoy art-works of Shimizu-san (see my post earlier), but not fluent in Japanese enough to buy his works, here’s a tip: start your favourite peer-to-peer program (eMule, eDonkey, Kazaa, etc) and search for “黒妖社”.

Of course, you can try any Internet search engine first. This is what I’ve found: under <黒妖社のしみずまさかず様から> – practically nothing by Masa, but lot’s of funny drawings. – absolutely not related to him :-)
That should keep you clicking for awhile.
