When the fine folks at reddit launch a Secret Santa gift exchange, you can bet that the resulting presents will be as geeky and varied as the reddit community itself. Nearly 40,000 people in 113 countries are participating in this year's edition of RedditGifts — a huge leap from the 17,000 who took part in the anonymous gift exchange last year. The annual event, which the reddit team is trying to get named Largest Online Secret Santa by Guinness World Records, began collecting participants Nov. 1. Secret Santas started sending their gifts Monday and many folks are already receiving their presents. From candy and Catan: Seafarers to glass pipes, participants are getting and sending all kinds of great gifts. "I got a handmade Kindle sleeve! A Star Trek Kindle sleeve!... I'm smitten," wrote redditer ashleygee after receiving her gift (above). "And now my Kindle can boldly go where no man has gone before!" Check out even more great geeky presents in the gallery above, and think long and hard about whether those socks you're getting your uncle really even hold a candle. (Disclosure: Wired.com and reddit are corporate cousins.)

Reddit gift recipient mattkuk got "a clock with the face numbers represented as mathematical equations."

"I got an awesome Arduino set!" wrote redditer Lodenk after receiving his gift. "I have not decided what to make yet — maybe a freeze ray, maybe a death clock, who knows! All I know is that, amazing new hobby, here I come!"

"[My Secret Santa] sketched memorable Star Wars characters in chronological order from the movies with amazing detail," wrote Exalted81. "My jaw dropped when I saw it. I could not think of a better gift for a Star Wars nerd."

Reddit user lacylola got an iPad. "This is amazing. I have a chronic pain disorder which limits me physically, and this is something I've been dreaming of for a long time," she wrote. "Unfortunately, my wonderful Santa is still anonymous. I wish I could send you a thank you, but this will have to do. THANK YOU THANK YOU THANK YOU."

"I received a nice assortment of videogames from my Secret Santa. I collect videogames, so it is a nice addition," wrote user UnderYourBed. "They also included a letter with some advice — keeping that to myself, though."

"A couple days before Secret Santa started, I was getting ready to buy my own gaming PC, seeing as how Black Friday was coming up and I felt like it was the perfect time to," wrote TayOKay. "Well ... my plans fell through and I ended up not having enough money to build it. :[ But then my amazing Secret Santa bought the entire thing for me! And more! BEST CHRISTMAS EVERRRR."
