Hopefully someone will know what im talking about and remember the image from the fast and the furious.
It was in doms rx7 when they met for the big race near the start. He turns on his sound system and you see in his setup, a screen displaying visualisations, like the bars moving when the music beats..
Anyway, i want to do similar to this, but the issue is, i'll already be running a screen upfront which will be connected to the incar pc..
Anyone know how i'd do this?
