great flexibility and sharing tool, 👯 !

Actually!

This workshop inspired me to start learning in-depth how the SVG XML is structured tonight. It felt like the emojis really should be in an "egg". So I grabbed Richard's original starburst background and threw an egg-shaped ellipse on top, shaded it around the edges, and then threw the emojis back on top. The sunburst gradient effect got shifted around due to making the sizes different to accommodate the egg... I figured out what happened but by then I already put too much time into this haha. Since it is SVG, there are many JS libraries out there that can let you manipulate the XML during runtime. You could in theory do something like

• Recreate the whole thing dynamically with the attributes so no storing of the images at all on the blockchain...
• Store a default copy of the image, such as the egg shape and the sunburst (its really just a mask over the background to give the illusion of the rays. So change the solid background to gray if it is dead, and switch out to the skull emoji
• You could animate the whole thing by rotating the sunburst
• Make the emoji pace and hop around when happy or fed

It really leads to many different things. Thank you for the inspiration!

Anyways for those who would like the base64 encoding for it here it is.
