Sprite LESS Snippet. Someone else has probably done this already, but I thought I'd share it nevertheless.

sprite.less

@spritePath: '../images/sprite.png';
.sprite(@url: @spritePath, @xpos: 0, @ypos: 0) {
  background-image: url(@url);
  background-repeat: none;
  background-position: @xpos @ypos;
}
