And how about replacing the dots (.) with underlines (_) and the exclamation-marks (!) with bars (|). So a hilbert would look like this: Old version: % filltest 8 8 ._. ._._. ._._. ._! !_. !_! ._! ! ._. ! ._. !_. !_! !_! ! !_._! ._. ._. ! ._._. ! !_! ! !_! ._! !_. ._! ._. !_. ._! !_._! !_._! New version: % filltest 8 8 ___ _____ _____ __| |__ |_| __| | ___ | ___ |__ |_| |_| | |___| ___ ___ | _____ | |_| | |_| __| |__ __| ___ |__ __| |___| |___| ... i think the visible effect will be much stronger. But nonetheless, i'd be interested in the source for the program. -- .odbo. .od88888888bo.
