Noticed any patterns?

[bjimster1]

I was thinking about what could possibly next year's game when I noticed there might be a pattern.

The pattern follows the FIRST logo; square, circle, triangle.

2003: Stack Attack (used rectangualar tubs for scoring objects)
2004: FIRST FRENZY (used balls as scoring ojects)
2005: Triple Play (used tetras as scoring objects)

Now I've only been part of this since 2004 but I was able to find out about 2003.
Please let me know if this pattern is consistant with earlier years of FIRST
If there is a pattern post what kind of scoring object there was.

Thanks
