Calling all landscapers!

I'm tired of searching, so maybe any of you green thumb-inclined folks might know.

Do you know of any sites online where you can virtually landcape -- as in drag and drop different plants to see how they will work together? (I hope I'm making sense, I'm on my first cup of coffee this morning.)

I'm going to completely replant the front of my house -- we cut down the scraggly cedar trees a couple days ago and I would love to play with different looks before going out and buying all the plants, shrubs, landscaping rock, and all that fun stuff.

Thanks in advance.

Those are a couple of free ones I found. I googled free landscaping software. There are several out there for 30 bucks, or so.
