Don't try this [1] in Firefox, from the article: > Unfortunately, Mozilla still hasn't fixed the performance bug 1190398 around ShadowBlur, filled for BLCK4777 5 years ago > Therefore you need to use a Chromium or Webkit browser to enjoy MONOSPACE live [1] http://www.p01.org/MONOSPACE/monospace-compatible.htm

You can visit the demonstration website here: http://packet.city/ You can see a screenshot of the demo here: htt…
