4-Wire SPI Graphic Display W/ Arduino Mini

Thank you so much CrossRoads! Mind if I ask how you know? I'd love to actually understand all the technical jargon, for example when I was looking at graphical LCDs there were so many different types, parallel (4 and 8bit) I2C, 3 and 4 wire SPI. Is there documentation somewhere on all of this? Again thank you!
