Just tried this yesterday and I got a Lucid from it last night.
Not saying you will straight away.
It is mainly for those who RC using their hands, people looking for an RC and people who want a new RC:

I obviously use my hand as an RC and always go lucid when I see my hands.
My fingers look all weird and wonky or I have like 6 fingers etc.

Trick is how do you RC during the day to make it look like your hands are like that so you see them in your dream and have the practiced RC help you become Lucid?

You Blur your Eyes and go cross-eyed. Funny huh.
Look at your hand now, and blur and go cross-eyed and say to yourself "wow look at my hand...I am dreaming".
You only have to do it for like 5 seconds to RC it each time. So it won't cause you harm. We all did it as kids.

I do this through the day and it worked for me.
