Mango Transparent Wallpapers, possible?

[Mattytommo]

I seen a while back on WPCentral that they were touting transparent lock screen backgrounds, they look pretty cool too. Now I see contrasting views whilst Googling whether this can be done or not, just wondered if anyone had achieved it here? (without unlocking) :)

Last I checked they worked in the Mango Beta as long as you don't have a lock screen password... I assume they work in the RTM too.

I can't test though as my devices all have lock screen passwords since my Exchange server requires it.
