One of my other hobbies is playing video games on my Nintendo DS. My spouse got it for me largely so I could play what was, at the time, the newest version of the game Animal Crossing. The finished mani in this post reminds me of the celebratory fireworks that happen a few times a year in that game. (Sorry in advance for the hideous state of my cuticles. I'm spending today moisturizing and getting them back into decent shape.)
I started with a base of China Glaze Hologram from the Tronica collection, which is a silver polish with a holographic finish. The formula was just the right texture: thick enough to easily control the placement, but thin enough to go on smoothly. I used three coats to maximize the sparkle, but it was basically opaque after two. I really like all the Tronica polishes that I have, and this one is no exception. Here's an indoor picture that shows the holo effect a little better. It still doesn't really show the full sparkly awesomeness.
And now, for comparison purposes, one more mani picture with a picture of an Animal Crossing fan (it was surprisingly hard to find a good picture of the AC fireworks online).
