I'm partial to builds with a retrofuturistic flair, particularly palmtop projects that imagine a portable past that never existed. Taking a leaf from the 'Windows where it shouldn't be' chapter out of the modder's playbook, one solo tinkerer has built a throwback handheld gaming PC that's rocking Pentium inside.
Built by maker Changliang Li, his Windows 98 handheld gaming PC plays all the contemporaneous hits, like StarCraft and Tomb Raider II (with of-the-era frame rates, too). Contained in a 3D printed, plastic shell spray painted an authentic shade of yellow that harkens back to its forebears, the homebrew handheld even features a Logitech rollerball mouse (via Hackaday).
