Should the repl show images?

[rafael.guerra]

This is what UnicodePlots does (quick & dirty example):

using UnicodePlots, Images
img = Gray.(rand(600,600))
imgc = gray.(img)
UnicodePlots.heatmap(imgc)

And there is the cool package by @ianshmean, VideoInTerminal.jl that outputs the video camera image stream to the REPL!
