Voodoo2: 3dfx’s final dedicated 3d gaming card | Custom PC #231
While it’s difficult to think of this as high resolution in an age where people are sincerely discussing gaming at 7,680 x 4,320, back in 1998 most people were using 14-15in CRT screens, some of which couldn’t even go above 800 x 600 in non-interlaced mode. The idea that you could actually run 3D-accelerated games at 1,024 x 768 (786,432 pixels), when the first Voodoo cards could only run at 640 x 480 (307,200 pixels), seemed astonishing.

Recreate the Victorian Fairy Lantern stage trick with Pico LiPo
The Pepper’s ghost illusion is actually much older than you might expect, and was first described in the 1500s. Although it’s not a true hologram, the eerie effect that it creates often gets called as such, and is occasionally seen as an advertising gimmick at trade shows and conferences. The illusion uses an artfully positioned pane of glass or plastic to reflect a concealed object or screen in such a way that the image appears to be floating, semi-transparent, in mid-air. The technique is also the basis of how an autocue works: since the illusion is only visible from a certain position, it’s possible for a public speaker to look directly at the text of an announcement without the text being visible to those people behind the transparent screen.
