Hi there, I wrote this back in 2006!
My Ds was an early walker (10 months) and he was very, very curious. I made him an obstacle course. Might be perfect for you now with crawling place to place and pulling up until he is also walking, moving and grooving! Have fun.
I set up an obstacle course for DS with baskets of surprises and many things are from around the house. I change it every week to keep it fresh. I made the living room in a circle, so I use chairs to block out openings so he stays in his course. It contains this:
Book area: On our coffee table I put books with flaps or pop ups, he loves opening and closing these flaps. He stands and does this with the books.
Ball area: I put small plastic balls, a semi deflated beach ball, a large rubber ball and a plush ball. Different tactile experiences with balls.
Wheel area: Cars, trains, wheel barrel, small plastic wagon--he loves wheeling these or just playing with the wheels
Basket #1: Lids from yogurt containers, spatula, wooden spoon, an old VCR remote control, an old phone that doesn't work, an empty washed out shampoo bottle, skipping rope, sheer scarves, plastic measuring cups (this weeks play stuff!)
Basket #2: Plush toys, building blocks, plastic numbers and letters, stacking toys, a fisher price doctors kit (he loves this and I highly reccomend it-it has a stethoscope, tweezer, needle, fake plasters etc... all baby proof and nothing to swallow, he mostly just chews them and handles them, but loves crawling/walking around with them for some reason.)
Cruising area: The couch with the lambskin, towels, blankets, pillows on it. He cruises around and loves to pull these things on and off of the couch.
Activity Table: This is an old toy passed down from friends with an older child. It is a play table with various "bells and whistles" things to turn and play, has music etc...I include a pic of him with it below.
He loves the baskets and mostly enjoys, taking things out an putting back in. I get involved and play too or just let him get to it and take advantage of being able to tidy etc...
I made one outside too- A toddler slide and climbing thingy, a wagon that I pull him around with or he mostly plays with the straps and the wheels, my exercise ball, a kiddy pool filled with balls or sometimes I put a wee bit of water -not much and let him have a splash with various sand/water plastic toys I got at Woolies back in June-like a spade, pail, rake etc...
Have fun, isn't this age great for play?
