Why I chose to be The Dude
One day, a thought hit me: what would the Dude look like if he were on the Grid? In many ways, Kevin Flynn in TRON: Legacy reminds me of the Dude, and it's not just Jeff Bridges. Although the fact that he said he was channeling the Dude, and how very Dude-like he is in his day-to-day life, does help.
Very quickly this idea became a fully realized costume idea. With a few minor changes, it's still the Dude, just on the Grid.
The big thing was the sweater. I knew I wanted to make it a black sweater with the pattern in white. I bought the yarn from Jo-Ann's and it turned out to be bigger than the pattern called for. I ended up using the pattern as a guide and figuring out details by looking closely at screenshots and counting stitches on the Dude's sweater. It was a lot of counting, but I think it's turning out quite well.
The identity disc is the other big part. I bought a Rinzler disc and a kit to modify it so not only would the color be right, but it would look more like a prop than a toy. (That's as far as I've gotten on the disc so far.)
