Looks great in chrome. seems the filter does not work in ff.
u/cantelope

i see now it simulates the changing of the seasons. very cool!
u/nonce

May I ask what FF are you on? I have FF 52.0.2 (on MacOS) and it seems to work.
u/donbright

color does not work on firefox / ubuntu. 52.0.1 64 bit, however it still looks amazing in black and white! i just love the whole effect of it, brilliant.
u/cantelope

@nonce I checked it in FF 45.8 on Win10 ( screenshot http://lookie.ml/i-12BLJO ), but Chrome is my primary browser. I've noticed that unicode tends to render somewhat inconsistently between browsers, which is why i avoid using it. But it's a great graphical hack when it works. :D
u/nonce

Oh my, it might not be consistent but I almost spat my soda all over my screen when I saw that screenshot.

'9em x'' seems to do the same thing as '9em sans' ¯\_(ツ)_/¯

this reminds me of an old carnival ride in my home town, it was called Phantasmagoria, no longer in operation, but you would ride thru tunnels of glowing pillar-gates. good times. nice job
