Well, based on what I have seen of UI concepts for Nintendo Switch on Reddit, I decided to create my version!
This is the main menu and dragging from the left you can see what's new on Switch universe (friends recent activities, eShop highlights). I know NS is not 3D based as 3DS, but I wanted to creat something more interactive, so content "jumps" from their tile on the main menu, moving when the selector arrives on the tile.
