Can you automate the drawing with a script? On X11, you can:

#!/bin/sh

# Position the pointer at the center of the dot, then run this script.

sleep 1

start=$(xdotool getmouselocation --shell)
eval $start

r=400
steps=100
down=0

for step in $(seq $((steps + 1)) )
do
    # pi = 4 * atan(1)
    new_x=$(printf '%s + %s * c(%s / %s * 2 * (4 * a(1)))\n' $X $r $step $steps | bc -l)
    new_y=$(printf '%s + %s * s(%s / %s * 2 * (4 * a(1)))\n' $Y $r $step $steps | bc -l)

    xte "mousemove ${new_x%%.*} ${new_y%%.*}"
    if ! (( down ))
    then
        xte 'mousedown 1'
        down=1
    fi
done

xte 'mouseup 1'
xte "mousemove $X $Y"

Interestingly, you can abuse the scoring system (not manually, only with a script). Since the mouse jumps to the locations along the circle, you can just use very few steps and still get a great score because every step you make is very accurate – but the result looks funny:

TacOS: an x86_64 UNIX-like OS from scratch
TacOS is a UNIX-like kernel which is able to run DOOM, among various other smaller userspace programs.

10 Hoaxes That Purported to Prove the Bible
Christian Bible inerrantists and literalists look to archaeology to back up scriptural narratives. Many discoveries have indeed proven that many things the Bible says are accurate. However, disturbing evidence, or in some cases, non-evidence, has also come to light. For instance, archaeology can find no proof that patriarchs like Abraham existed, no indication that a […]

@lyse@lyse.isobeef.org I walked under 25°C during my lunch hour today, but with a sunshine that could fry an egg if dropped on the asphalt. I told a friend in Manila about it, and she told me that 25°C is Winter/Christmas temperatures for them. I felt cooler right away. :-)

The subjective charms of Objective-C
To argue that Objective-C resembles a metaphysically divine language, or even a good language, is like saying Shakespeare is best appreciated in pig latin. Objective-C is, at best, polarizing. Ridiculed for its unrelenting verbosity and peculiar square brackets, it is used only for building Mac and iPhone apps and would have faded into obscurity in the early 1990s had it not been for an unlikely quirk of history. Nevertheless, in my time working as a softwar … ⌘ Read more

How big is VMS?
This question was asked during my Boot Camp presentation last fall in Boston, and over the past 35 years dozens of times people have asked, how big is VMS? That translates into “how many lines of code are in VMS”? I thought it was time to at least make a stab at pursuing some insight into the answer. I wrote some command procedures to count the number of source lines in .B32, .B64, .C, .MAR, .M64, and .S files.

Casting can be counterintuitive. Studios often hire male actors for female characters and vice versa.
