I'm not quite sure that is an actual term, but it is one I've started to use to describe many of my projects lately.
Another geek crafting project I worked on last year but never had a chance to blog about was this adorable TARDIS phone charging station/felt box.
Bless all those folks that come up with these things. I so enjoy tackling them.
My little TARDIS ended up just becoming a small box - I decided not to cut the small whole in the bottom to allow it to become a phone charger.
