The Foundry is offering up a demo of Modo and MeshFusion through referral links for those interested:
http://community.thefoundry.co.uk/trymodo/?referral=Warren+Marshall
I don't get anything out of that referral other than some free training video so I don't have some nefarious goal other than spreading the MeshFusion love.
Click, click, enjoy! Also, they say if you've evaluated Modo previously, they'll reset your timer...
