Matte painter Sven Sauer has designed two visual illusions to promote “Halloween Burg Frankenstein,” which is a live horror event held in a renown castle in Germany. The digital artwork (shown at top) cleverly forms a skull, and it seems to be inspired by past artwork of Charles Albert Gilbert, Salvador Dali, and others.
