OpenIconic

OpenIconic is an very nice open source icon set. Those icons have been integrated into the link::creole[creole parser], so you can use them out-of-the-box.

You can use the following syntax: <&ICON_NAME>.

@startuml
title: <&heart>Use of OpenIconic<&heart>
class Wifi
note left
  Click on <&wifi>
end note
@enduml

It also works with link::salt[salt, the graphical interface designer].

@startsalt
{
  Login<&person> | "MyName   "
  Password<&key> | "****     "
  [Cancel <&circle-x>] | [OK <&account-login>]
}
@endsalt

The complete list is available on OpenIconic Website, or you can use the following special diagram:
