Pork-chop plot showing total delta-v needed for moving from Ceres to Extropia.
It does not make use of Oberth maneuvers or multiple orbits around the sun, so these values are a bit higher than they would be in a real mission. Given that these are intended for use in a roleplaying game, that is probably enough precision anyway.
Very rough estimation of the radiation dose/hour one meter away from a fuel array filled with spent light water reactor fuel as a function of time. The initial composition based on table 1 in aries.ucsd.edu/snowmass/SG-A/ans96-transmutation_paper.pdf
and the initial radioactivity by figure 1 in

The green lines mark the acute effects after one hour exposure. I have added the contributions of various isotopes in blue, but not taken daughter products into account.
The roleplaying game 2300AD has a fairly elaborate planet generation system. This is the results of generating 10,000 planets in the inner, life and outer zones using the rules.
One of the surprises is the larger fraction of gas giants in the life zone compared to the outer zone. This occurs because they are more likely to get a heavy core than in the outer zone, where an ice core has a hard time getting enough gravity to attract a dense atmosphere.
I made a cut-off at 100,000 km diameter; the gas giants go all the way up to 500,000 km. That big giants would not actually have that radius, since the pressure would cause them to become denser. Their likely diameters are going to be Jupiter-like, around 133,000 km.
Zooms of the Mandelbrot set around a point projected so that the distance to the point forms a logarithmic scale. Details on the left edge are ~10^15 times smaller than on the right edge.
The rightmost black blob in the pictures is the main "continent" of the set. Satelite sets of different sizes can be seen linked by fractal chains of varying complexity.
The colors are set using the distance estimator method.
Different projections of Bucky Ball(truncated Icosahedron),Dodecahedron,Icosahedron and Rhombic Triacontahedon .First column is hyperbolic,second is original polyhedron,third column is spherical.What can I say about last column.

An experiment in coupled "reaction-diffusion systems" (actually, using a mexican hat convolution more akin to field models of neural activity in the cortex). There are two variables with sigmoidal transfer functions, and an adaptation variable that causes the pattern to shift.
The Mammals, displayed using a further development of my Voronoi treemap code (now with nicer borders and more robust calculations). Each polygon represents a mammalian species or group of species, distributed inside larger groupings.
Generated using software I developed to convert photos into Lego mosaics. This portrait comprises 91x96 bricks, which equates to a size of 728x768mm if realised using standard Lego.
The portrait was derived from an original photo by Peter Francis of his wife Sally and is used with permission and appreciation.
The software was originally developed using Matlab but has now been implemented as a Windows/macos app using Qt/C++.
Plot of travel time as a function of delta V for a trajectory from Mercury to Venus. The colors denote different start dates (red late in the year).
Note that there is an asymptote to the left: below a certain delta V a ship cannot reach the destination. There are many possible low delta V trajectories, but they all take more than 30 days. Ships faster than ~150 km/s can begin to press this travel time, and beyond 900 km/s delta-V the trip can be made in a day.

Plot of travel time as a function of delta V for a trajectory from Mars to Extropia. The colors denote different start dates (red late in the year).
Note that there is an asymptote to the left: below a certain delta V a ship cannot reach the destination. The right end of the curve is due to lack of sampled trajectories with very high delta V, the actually curve continues indefinitely.

Today I finally made progress with a GUI for ginger. A command window is for people like me who know the system inside and out and need to perform low-level functions.
The satellite windows visualize the different experiments being conducted in realtime and allow the users to draw the data from across a network if needed.
The code for the sattelite windows is easily adapted to fit any allspice node and run alongside the existing windows.
The whole thing is written in matlab using GUIDE. I know I know, its not fancy but at least its cross platform!

Roti, kapda aur dawa
Ghar rehne ko chhota sa
Muft mujhe talim dila
Mein bhi Musalmaan hoon wallah
Pakistan ka matlab kya
La Ilaha Illalah…
Amrika se mang na bhik
Mat kar logon ki tazhik
Rok na janhoori tehrik
Chhod na azadi ki rah
Pakistan ka matlab hai kya
La Ilaha Illalah…
Khet waderon se le lo
Milen luteron se le lo
Mulk andheron se le lo
Rahe na koi Alijah
Pakistan ka matlab kya

Topography maps of Titan based on the data in Lorenz et al. "A global topographic map of Titan" Icarus 225 (2013) 367–377.
The maps are based on small strips of Cassini radar observations that have been interpolated with splines; the real topography is of course more fractal. The elevations are fairly flat, with higher regions at the sub- and anti-saturnian points.
The movement of the "economic centre of gravity" across history.
The centre was calculated by taking the Maddison historical economy dataset and calculate the GDP-weighted average of the country locations (taken from the Nationmaster database). This point is located inside the Earth, so it was projected radially onto the surface and plotted with a Lambert projection.
