If you're a gamer or a geek in general, you might want to incorporate some of your true loves (other than your fiance) in your wedding.
Everyone's seen the Mario cakes, Star Wars cakes, etc...If you want a slightly more subtle touch, you could get a cake topper that refers to your hobbies. People who are in the know will appreciate it, and people who don't know the specifics of your secret shame will find it amusing to have your geekdom outed.
All of the following toppers were handmade by real people, too, so if you get a chance go check out their shops and flickr pages. Thanks to all of the artists for giving me permission to use their photos, as well!
pair of Portal 2 toppers made from legos... This one was made by Tyler of Legohaulic
If you're more into Zelda (like I am) then you could do something like this topper, which technically isn't correct because Link and Zelda are "just friends," but we'll overlook that due to its cuteness.
Anna Cho of Anna's Crafts made these. She has two etsy shops, one at http://www.etsy.com/shop/annacrafts and one at
these Star Wars toppers. Check out her flickr page!
these Batman cake toppers. I love the mask on the bride. These were made by Kathy Bocchino, whose etsy shop is found at http://www.knottingwood.etsy.com
And the hardcore Star Trek fan can also have his and her day. This topper proves that Trekkies find love too...Maybe the Comic Con Convention can be a matchmaking experience if you play it right.
