OrbitMaster Improvements and Sample Scenarios

I've had the opportunity over the past few days to make a few changes to my OrbitMaster applet, so I thought I would outline them here.  The major changes were to the graphical interface, making it look and function better on small screens (like the low-resolution format my MacBook Pro usually defaults to when I plug it into a projector).  Anyway, here's what it looked like on a smallish screen BEFORE the recent tweaks:

As you can see, the time-controls and the orbit-parameter labels were taking up far too much space; the actual orbit-parameter sliders had shrunk to be almost unusable; and the "Fine Control" checkbox disappeared completely.  Here's what I've done to make it better:

Fonts are smaller, but I don't think they're too small when you look at the actual applet.  And everything remains functional at 80% of the width shown, too.  (The "Lock" function disappears, but being able to lock down the orbit-parameter sliders isn't something you need to do frequently.)  How does it look?  Let me know if you have any feedback.

If you're still reading this, then perhaps you'd be interested in some sample orbit I've visualized in the past?

• OrbitMaster - This default page is really the orbit for asteroid Ceres, but without any of the stress of feeling like you're messing with another rock's orbit.  Feel free to play around!
• 2008 TC3 - The object that hit over Sudan with only 24 hours' notice.  Let it orbit a few times at perhaps 10-day time steps and in October 2008, watch OrbitMaster's impact-detection algorithm jump into action!  The applet does also calculate how much speed the object gains as Earth's gravity pulls it in, although it doesn't actually alter the orbital parameters in the process.
• Apophis - Named for the Greek god of darkness and chaos, thanks to the 2.7% probability of Earth impact that had at one time been predicted for April 2029.  Run time forward at time steps of 1 month or less and you'll see that there's a close-approach detection algorithm as well!  Center on the Earth, click the "Fine" checkbox and zoom all the way in, and you'll see Apophis cross the Moon's orbital distance (yellow circle) and that of the Earth's geosynchronous satellites (red circle).
• Killer Asteroid - A fictional asteroid on an Earth-like orbit, constructed to have minimal speed with respect to the Earth for most of its orbit.  But you'll see that when the impact-detection algorithm kicks in around April 2009, the speed increases until impact due to Earth's gravitational pull.  The impact speed is approximately 11.2 km/s, the escape velocity from the Earth's surface.  Which is exactly what you'd expect from an object dropped "from rest" up in space!  This is the slowest that anything from up in space can hit the Earth - without atmospheric deceleration, that is.
• Killer Comet - A fictional comet on a retrograde orbit, constructed to hit Earth with maximal speed..  It doesn't pick up much speed from Earth's gravity (less than 1 km/s), but this is still an escape-velocity scenario!  Because the comet was "dropped from rest" from the outer solar system, when it reaches 1 AU from the Sun it is traveling the same 42 km/s that would be necessary to escape from the Sun's gravity if you started at 1 AU.  Add this to the Earth's 30 km/s orbital speed and you get the 72 km/s impact speed of this comet.  It's the fastest that anything from up in space can hit the Earth - unless it came from outside the solar system!
