Every so often I do an Etsy search for "tron" just to see what comes up. Sometimes I even find stuff I like or think is funny.

Like I kinda want this shirt: http://www.etsy.com/listing/72496111/tron-user-tshirt-black-with-white-ink?ref=sr_gallery_19&ga_search_query=tron&ga_search_type=all&ga_facet=
This notepad is kinda cute and clever (but would be easy to make yourself if you're like me and have a bunch of old floppies from middle school that you haven't a snowball's chance in hell of getting the info off of anyway): http://www.etsy.com/listing/72260096/encom-floppy-disk-notepad?ref=sr_gallery_37&ga_search_query=tron&ga_search_type=all&ga_facet=

And, of course, if your User knits:
TRON MITTENS. What more can I say??: http://www.etsy.com/listing/38352579/tron-mittens?ref=sr_gallery_18&ga_search_query=tron&ga_page=1&ga_search_type=all&ga_facet=
Or socks: http://www.etsy.com/listing/51315819/tron-sock-pattern?ref=sr_gallery_35&ga_search_query=tron&ga_page=6&ga_search_type=all&ga_facet=
