The original name of my image is "Globos Atomicos" (which I have traslated to "Atomic Balloons" to fit the language restriction of this web)

I have made this image using Inkscape 0.48. The original .svg is ready to be downloaded and I have uploaded 2 more .png for preview.

Feel free to modify the .svg to fit your needs or to make any improve (in this case please let me know, so I can see the improvements and use them)
