It's the Snapchat filter which has taken social media by storm, and provides an answer to the question you didn't realise you needed to know: what would I look like as the opposite gender?
If you've been anywhere near social media this week you''ll have seen friends and family members post photos giving insight to what they (potentially) would have looked like if they were the opposite sex.
Sure, tech-savvy Aunt Doris' image of "Don" may leave you with nightmares but it's easy to see similarities between your loved ones and their altered image. But can you say the same for these prominent Canberrans?
Slide the bar on these images and see how you go.
Andrew Barr or Andrea Barr?
Is it just me, or is Shane Rattenbury rocking the long locks?
Although he may have some competition in Alistair Coe for best alter ego hairstyle.
The Snapchat filter didn't quite take away ACT senate Labor candidate Katy Gallagher's hair, making this one a particularly easy one to guess.
And Meegan Fitzharris' hair makes her pretty easy to identify as well.
Meanwhile Liberal senator Zed Seselja's pearly whites may be a giveaway here.
The same can be said for Andrew Leigh.
The fun can't just be kept to the politicians. Is that you Jarrod Croker?
Meanwhile David Pocock is little more distinguishable with his head gear giving him away.
