I went to Kinko's to get the mosaic printed out. At 21x14 inches, it cost me just shy of $20. That seems a shade expensive.
Speaking of shades, the image which printed out on my home printer tolerably well is awfully, awfully dark when printed out at Kinko's. I'm saddened by that. I know that screens and print are different beasts, but perhaps my printer has some special settings that I don't know about.
