To be honest, pretty much every day is TRON day to me.
I often greet people by saying "Greetings, programs." It is not uncommon for me to greet perfect strangers like that.
I use the phrase "Mr. high and almighty MCP" when I'm talking about control freaks who get on my nerves.
I think of window screens (used in warm weather) as mini game grids for flies.

I'm know to say "c'mon you scsi data - be in there" when I'm looking for lost files on my computer.
Every time one of my computers at work starts getting sluggish or reboots itself, I blame those damn grid bugs.
When I see motorcycles on the road, I always mentally envision them escaping the game grid.
When I drive to work in the morning and it's dark, sometimes I see recognizers on the road. Actually, they're just school buses, but the reflective tape on the back of some of them closely resembles the shape of a recognizer. I really have to try and snap a photo of that sometime. I've been meaning to bring this up in its own thread. Pretty cool looking, actually. But I bet I'm the only guy on the road seeing a "recognizer" instead of just a school bus with reflective tape.
I often think of my drink as an "energy drink". Sometimes, I even like to drink it out of a frisbee (or identity disc) like they did in that one scene in the movie.


Uh... not sure I should share that with people though.
As a kid, I would try and throw frisbees like they did in TRON - with the full arm motion from the side, holding the frisbee with my hand on the outer edge and the frisbee under my arm... if that makes any sense. Every time I threw it like that, it just curved heavy to the right and then hit the ground early and rolled away.


Never stopped me from trying though.
So yeah - every day is TRON day. It's just a question of your geek-level. Mine is pretty high.
