The actual symbol exists for what you want to identify and appears in the International Symbol Dictionary to indicate an otherwise unspecific (miscellaneous?) place of interest. Some interpret it as a view of a castle from above, while others trace its heritage to the Bowen knot. It was rarely used and fell into obscurity.
It’s called the command key, the splat, the pretzel, the propeller, the cloverleaf, or the squiggly key: the cryptic ⌘ that Mac users tap ten times a day. The symbol is familiar yet cryptic, but like everything Apple, there’s a legend behind it.
Apple chose the icon for this and appropriated it for their "Command" key to replace the logo originally appearing there. It was the familiar clover-leaf design.
The Apple Command key (or, as you might better know it, ⌘) has a beautiful and clear history. Originally, the ⌘ key was an Apple symbol instead, but Steve Jobs thought that using the Apple logo as a keyboard shortcut in the original Macintosh’s menus was “taking the logo in vain” so he tasked the great icon designer Susan Kare to find a solution. The symbol she chose was the traditional clover symbol we all know today, chosen because it is commonly used in Scandavaniva to indicate a tourist attraction or place of interest.
Since that's what it's for, use it. Why reinvent the wheel? Why create redundancy? Take back the design; it was grabbed from our legacy. Justice for all!
