I don't have as much as some people I know but I have enough that no-one coming into my living room would doubt that a sci-fi geek lived there! I love the popfunko figurines and I have a small collection of some of my favourite characters from them - there are Marvel characters guarding my comics & graphic novels, while a couple of the DC gals guard my un-watched DVD pile. And...I have the car from Ghosbusters in Lego! Oh and I bought an art print from one of my favourite webcomics, so I have that framed on my bedroom wall too.

I've been in Doctor Who fandom to a greater or lesser extent since I was a small child - so about thirty years now :S - so I have accumulated quite a collection over the years. Most of the older stuff has gone now - I used to scrapbook newspaper articles about the show when it was off-air, and I had some toy aliens that school friends bought me - but I still have a TARDIS teapot and a Dalek plushie that an ex-girlfriend bought me, and a quote plaque on my wall that my parents got me as a house-warming gift.

(I also have a collection of geeky t-shirts, tie-in books, coffee-table style 'art of x' books and script books...I was a film student so the line between fandom and academic interest is arguably a bit blurry here.)

My favourite though is probably my cuddly Gizmo from the Gremlins movies, he always makes me smile.
