I just had a great idea! You know those sand paintings some people do? The ones that are doomed to be cast out into the wind? Well, there's that solar sinter thing I blogged the link to on Tumblr yesterday, so... maybe not that one, but using a laser, here's my idea: Do a sand painting on a thin slab of some substance like stone or concrete that won't melt or catch fire under a laser hot enough to sinter sand. Not sure if stone or concrete would work, but something should work. Anyway, do a sand painting on this substance, then use the laser to sinter the sand in place.
Not sure if it would work, how it would work if it did, or what the end result would look like, but it's worth a try. Wish I had the skills and money to try it myself.
