If you search for anything Pokémon related from time to time, you may very well have come across the work of PLDH‘s adminstrator ‘TopHat’, who tasking themselves with the quest of making a minimalistic wallpaper representing every single Pokémon.
Having recently come across their work myself as they’d made a wallpaper representing all of the currently announced Pokémon for X & Y, I was amazed at how each of the wallpaper representing every Pokémon of every generation (and their alternate forms, if they have one) all stuck to the same clean, beautiful minimalistic style. It was inevitable at that point that I would save every single one of them to my laptop and set them as my wallpaper, with it changing automatically to a random one every 30 minutes.
TopHat has blessed us with the ability to download all of them and they look bloody spectacular as wallpapers. I highly suggest you download all of your favourite Pokémon – if not the whole bunch in its entirety like I did, because they truly are stunning.
