Some of his donor rewards include small postcards altered to fit the EdgePonies motif that will be mailed from Dublin. The $50 donors will have their names toasted over a glass of Guinness in an Irish Pub. The rewards get more grandiose the higher the donation level.

Westwater is going to Dublin this spring and to Iceland this summer to continue his work on a series called "Edges."

He describes his style as post-minimalism with an emphasis on hard-edge painting. He said his inspiration originally came from Kasimir Malevich's cubism and abstract paintings.

For about a decade, Westwater was fixated on Malevich's square -- as well as the occasional rectangle -- pursuing a post-modern "art about art" cycle, he said. Then, along came the parallel oval.

The oval is seen throughout Westwater's College Station home, where he lives with his wife, Naomi Sachs.

In his more recent pieces, Westwater has started to turn his focus back to rectangles and the idea of borders. He said his residencies in Dublin and Iceland are a manifestation of that concept because the countries are on the farthest edges of Europe.
