I learned a new word today: linkware.
I found this site: Ten Two Studios and this related site: 2008 March Countdown. At the second site there are posted some free downloadable images; the artist only asks that you link to her site from your own blog. Then you can download, (quoting the artist), "to your heart's content".
I especially liked the Irish words; see the 2008 March Countdown link above. Lots of potential fun methinks with that.
It's available through tomorrow, March 23. So, I hope you see this soon. :)
