I love the elegant Lastik folders. But as the Lastik theme contains only a few icons I extended it and added some icons so that it matches my needs. Apart from the trash and the arrows the home and the desktop icons are taken from the Reflektions theme and inspired by them I created a few similar icons.
As usual for my icons themes the iconvert script is included to generate the missing icon sizes after installation. Please execute it manually in the folder the theme is installed to (usually ~/.kde/share/icons/simply-elegant).
