Do not adjust your set - Instagram has undergone a serious redesign.
The Facebook-owned image sharing service has switched up its hipster instamatic camera vibe in favour of a more vibrant, acid-fuelled logo.
Instagram's partner apps, Layout, Boomerang and Hyperlapse, have received similar trippy tweaks.
While the new logo is dividing opinion (a quick Twitter search of #instagramlogo reveals the extent of the polarised discussion), the app itself has received a favourable lick of new paint; a clean black and white colour scheme with a focus on photos and videos that doesn't interfere with navigation.
No new features, no fancy functions - just a fresh look from the most popular image app out there.
