Those artist's renderings were done by the pool designer so i don't have access to that software, but a quick google shows that everyone and his dog is trying to sell versions of it.
There are even a few versions that are free, sort of.

The spa is seperate from the pool in that I will be able to push a button and heat the spa without heating the pool and versa visa. Only the water overflow from the spa (when my fatass gets in) will go to the pool.
The designer said that with a spa this size and the heater I bought, I should beable to take the spa from 50 degrees (dead of winter) to 95 degrees in less than an hour. Caa-ching.

Hopefully I won't lose the remote. Just what I need, another remote. I wonder if I can get it to work my TV, satellite dish, DVD, home theatre, ceiling fan, etc.

By design this pool is relatively shallow, only 5 feet at the deepest part. It's also relatively small so it won't be as expensive to maintain. It's just over 35 feet long. Just right for a party pool or for kids to splash around in and maybe play some volleyball.
No diving, no deep end to worry about, I tried to make it as logical as possible even though a new pool is not logical by definition.
