What player is this?

I know it!

The visualisation is called Spec'n'Hopp, was originally for an old player called Sonique. You can get the vis plugin for XMPlay and Winamp according to these pages:

(I'll also add that for module listening under Windows, use XMPlay. Just don't even f**king bother using Winamp for MOD playback, its "replayer" is a festering turd of bad quality and poor accuracy. XMPlay's playback routines for PT/XM/IT/S3M modules are excellent, and if you use the Delix plugin, you basically have Delitracker/Eagleplayer and all its replayers emulated in a virtual 68k environment courtesy of UADE - Amiga module playback on PCs doesn't get much better than that.)
