As well as rounding your images, you can now add your text and icons to DiskThing and have them perfectly centered. The rotation feature also makes it great for creating labels and pricetags, and the new hover effect option adds even more style and functionality. For a responsive less-featured version, see CircularThing.
Examples are in 4 column fill layout, 250 px thumbnail backgrounds, width set to 150 px, with 2px, primary color borders.
Idea is demonstrate hover feature that zooms the background. The drop zone contains (1) Heading, (2) Image rotated right, (3) smaller image rotated left, (4) F3 Button with icon. The "Disks" are constrained to be 150, 200, 250 and 300 px wide eac (500 px max).
