+first:
+- split rocket and exhaust into separate elements
+- add camera container around stars + rocket that handles rotation (points
+  stars and rocket in same direction, makes animations easier by only requiring
+  left/right/width properties to be animated)
+- animate exhaust flames
+- create slope poller to determine rocket flying angle (either calculate from
+  tickers or pull from some website, e.g. bitcoinwisdom, in the latter case
+  also try to get the tickers from there)
+- fix ticker polling
+- properly scale dashboard
+- make it work on mobile (good element dimensions + smooth animations)
+- add more states for different slope levels: divide the flying angle in
+  segments and assign a state to each segments, with transition animations
+  between each state
+
+later:
+- move/scale moon depending on market
+- replace images with final ones of lower resolution (maybe use css background
+  instead of img tags)
+- bitcoin donation address + QR code
+- add easter eggs
+- add sound?
