This site has them [link], and there is an extension so you can open a small pop-up window in your browser to search for them. You even can drag and drop them from the pop-up into your comments. Also, there is a place in the pop-up window where you can save the ones you like and use most often. It is a marvelous idea and implementation of a pop-up extension. I use Chrome as my browser. It is a piece of cake!
Enjoy and use with great pride and lots of fun and laughs!
BTW, you should write the sentence as "Where do you find such icons?" This is common English usage. If you need any help with English, I will be glad to do that for you too.
Keep up the fantastic and marvelous work. You are a wonderful artist too!
