This is cool! I like Kiger mustangs, the one shown here is gorgeous (and it reminds me of Spirit) but they come in all other colors! The falabella ponies are the smallest know to man, reaching to only about 3 ft. Tall when fully grown! Pony of the Americans is a awesome horse for kids. They have a perfect slope in their backs so it's easy to stay on, even bareback!
There are so many tricks you can teach your horse. There are all the usual ones like kiss, hug, bow etc, but also have a think about teaching your horse some USEFUL tricks. These can make life a lot easier (and safer) around your horse.
Dapple gray Lusitano horse. I remember the song by Peter, Paul, Mary, "All the Pretty Little Horses." One of the lines is about "dapples, and greys, pintos and bays..." Maybe they were singing about a Lusitano?
