I don’t really make them fast. In fact, I haven’t done many new ones in recent years. The one above is the September image from a little Magnaclam calendar that I did for 2009. If you’re interested, all twelve of the monthly images are in the Cigar Lounge in a thread called: Magnacalendar: Year in Review (or close to it; I’ve found it before with RO’s search function, flaky as it is). The images were relatively easy to make simply be resizing the individual Clam images, flipping and rotating as need, and pasting to the image under construction (in Paint).
The story behind the Magnaclams started with a chat with my late online friend Sarah (there’s a memorial for her stickied in Site Announcements). We frequently chatted about sci-fi and things, and sometimes did silly double-talk debates. Well, one night, she made an offhand reference to giant intelligent clams. We went back and forth a little on it, with me as pro-clam and her as anti-clam. Ultimately, I ran with the concept, and that’s the origin of the Magnaclams.
