changing the view of tiles

[Ratinahat]

I read somewhere that you could change the view of tiles. Meaning that you could rotate tiles so the tile was facing a different way. I was just wondering if this is true, and if so how do you go about doing it.

Thank you in advance for any help you can give me.

You have been able to do this since pets by rotating them with the < and > keys
