I have a similar board made by mib-instruments and bought from ebay years ago. It has been my standard spi test tool because it's so easy to work with. http://www.ebay.com/itm/Nokia-5110-LCD-84x84-dot-martix-backlight-PCB-RED-/320684678723 (specs http://i1119.photobucket.com/albums/k636/mib_instruments/diy/LCDC2A0SPEC.jpg)
I wanted another one so i bought the sparkfun item but it doesn't quite work: it flickers and blackens occasionally but my graphic never shows up. Is there a bulletproof arduino sketch I could use to test it?

That's fine but there's nothing on the description of the module that indicates that the accuracy is poor. It's not ok to be selling a clock circuit that doesn't keep time fairly accurately without a big caveat on the product description page. Mine is losing a second every three hours and your reaction is "oh well, we have a better one" - not ok you guys.
No public wish lists :(
