when I became an uncle, and my mate had his kids too, he wrote me a birthday card and called me Unkle'G'sif in a sort of graffiti style (he is an artist), and it just stuck
Answer: Some say TWAIN stands for "technology (or toolkit) without an interesting name," but that's a myth. What matters is what TWAIN does. Released in 1992, Twain is the interface standard for Windows and Macintosh that allows imaging hardware devices (such as scanners and digital cameras) to communicate with image processing software. Prior to TWAIN, image acquisition devices all came with their own proprietary software. If you wanted to work with a scanned image in a different application, you had to save the image to disk first, then open the application of your choice and re-open the image there.
but really, it started when my friend back at Uni pronounced my name weirdly. Martin + Twain = Martwain. Twain for short. He is weird, but coincidentally he shares the exact same birthday as me - it'll be 11/11/11 this year my first binary birthday (with the exception of last year and the year 2000)
