What activities can I entertain with?

My daughter is almost 3 months and I'm trying to find new things to do with her. Hoping other moms can give me ideas here. On a regular basis I talk/sing to her, lay her in the pack and play under a ceiling fan that I hung stuffed animals from (she LOVES watching ceiling fans), put her in the snugga bunny swing, set her in the bouncer chair as our dinnertime center piece on our table, show her toys that light up and sing, lay her on a pillow and practice her setting upright and laying back down with my help. Other than these same things what can I do to entertain her and teach her new things? Running out of ideas.
