The idea with this huge keyfob is that it will be so big and annoying that you will never misplace it.- It is so big that you can't put it in your pocket and forget it.- Big and shiny so it will stick out on a messy table or desk- Visible from a long distanceWorks great if you have children/pets who likes to snatch keys and lose them in the most peculiar places. (under a rug, in the middle of the lawn, etc.)I use this for my USB dongles (one is the excellent Galaad and the other one is Moshidraw, the infamous steaming pile of dung) so I never have to search for them.I also enclose the SolidWorks 2014 source fileI saw this idea at a previous job where a shared key was attached with a big chain to an heavy piece of scrap iron painted in red. It was so heavy and annoying that you never forgot to put it back where it belongs, plus you could clearly see who had it.
