Adorable baby mobiles?

The time has finally come to decorate my child's crib. I am overwhelmed and excited. My first baby could not get what i wanted him to have as we were not very well off. This time i would not let that happen. My second born is on his way and i want him to everything he deserves. I want to know where i could find really adorable baby mobiles for the babies crib. Something unique and eye catching. My first son is 2 years old, I would be taking him along for the shopping spree. Do you think i should ask him to choose something for his brother. I dont want anything too blinding also. What is the latest in fashion. Any ideas?
