Giving gifts to colleagues?

I am considering to buy a (small) gift for each one of my colleagues for Christmas / New Year. Just as a fun thing to do. Wouldn't be very expensive gifts, more like 10 dollar each. However, I am wondering if this would not be seen as weird?

We are doing a secret Santa anyway; but I would buy another gift for each of my colleagues just to make it a bit more fun. It would set me back about 100 dollar (which isn't an issue), but I wonder how my colleagues would perceive this. Would they think it's just strange or think there is something up (perhaps think I have ulterior motives)?

What is your opinion, how would you react if you got a gift from a co-worker like this?
