Thought I'd give this a shot:
https://steemit.com/steemitjam/@brandonsadventur/my-entry-for-steemitjam-logo
My page includes a download link to the GIMP file and I also exported the layers out as separate PNGs for compositing. All source materials are included, even the fonts, and I exported "Neonified" numbers as well.
Hope you enjoy :)
