Triforce
is a soft synth from Tweakbench for producing classic Nintendo
Entertainment System-style sounds. No gimmicks here: square, triangle,
noise oscillator, go to town. The simplicity is beautiful, and the
price is free. We've mentioned the superb stuff from Tweakbench before,
but this deserves special mention. (via Brad Sucks and Future Boy)

Sorry, Macsters: Tweakbench swears no Mac version, ever. Blame SynthEdit.
