孢子团队 Spore team 发布了 ParticleMan（右键下载）粒子系统，虽然不能算什么大新闻，但对于一些使用惯粒子系统的玩家们，还是可以尝试一下的。它可以模仿出星云的形成和宇宙中的无重力状态，大家可以从中研究一下脉冲星和黑洞的产生。（貌似很专业 - -）

ParticleMan has the following elements:

• Particles — point masses which interact with each other
• Gravity Wells — fixed point masses which attract or repel particles(depending on magnitude, which can be negative), but do not move or change mass without user input
• Particle Guns — sources that spit particles out at a given angle and velocity
• Gravity Wells and Particle Guns may only be placed on the green grid in the z=0 plane.
• The Iso Surface — an isosurface geometry object derived from the positions and masses (which act as field strengths) of the particles.
