The guys behind the generative KOAN software have developed a pair of new applications, one of which is designed to free the lyrically challenged from the burden of stringing words together in a semi-meaningful way (the other - noatikl - is a generative music app).
The delightfully-named liptikl provides a simple interface into which you enter words or phrases.
The software then generates a stream of combinations in the meter of choice that can then be edited and recombined to your liking.
As with all generative software, the results are mixed. Most are going to be useless, but repeated clicking may reveal a gem or two.
At $99 for a commercial license, it's a bit pricey, but if you don't plan to reap any reward from the results, it'll set you back 59 smackers instead. Not essential, but interesting.
