This is my headcanon about the Crystal Mirror:

A long time ago, when he was young, Starswirl the Bearded came across a strange cave. Inside was a portal. When he stepped through it, he found himself in the human world. But he remained a pony. He was in Ancient Greece in our history. Starswirl made a horrible discovery. Humans were using the ponies of this world as slaves! They had no sentience, no free will, and were kept in small stables. He raced back through the portal to Equestria. He wanted to know more about these strange two-legged creatures, but didn't want to risk putting ponykind in danger. So after sealing the cave, he built the Crystal Mirror, and placed a spell on it:

"Through this mirror, ponykind shall travel to the world of these beings called humans. But they shall become human to avoid capture for slavery. And, should a human pass into our realm, they will take the form of a pony to avoid being caught by the Princess' Royal guard. When each returns to their own world, they shall transform back to their original bodies. This mirror will open every 30 moons for three days at a time. When that time is over, the portal will close and stay as such until another 30 moons have passed."

Using the mirror, he took on human form and learned a lot about our world. He recorded his findings and shared them with everypony else. At first, they didn't believe him until a guard fell through the mirror. After that, Princess Celestia employed several of Canterlot's greatest minds to our world to record information about the advances in our civilization, so they could be recreated for use by ponies, and in their image. This explains there are hydroelectric dams, video games, bowling alleys, and scientific equipment like the stuff in Twilight's basement in the ponyverse. Some things, mainly cars, planes and certain other modes of transport weren't recreated because the ponies only know how to pull carts and drive steam trains. This may help to keep peace with nature.
