Just as I thought SOMA was fading, I heard from Paulo Brina of Belo Horizonte, Brasil.
The story he told was BIG SOMA
Joining the rest of us, SOMA maniacs, Paulo was tired of the old 7 piece soma,
so he began to play TetraSOMA, using 4 sets = 28 pieces = 108 cubes.
The tetra set, home made, stainless steel (it's polished, so, it's hard to take photos) 
001 bloc 2x7x9 = 126, so we have 18 holes/gaps . 
002 A 5x5x5 cube would make 125, so we have 17 gaps, 2 are hidden 
003 Another 5x5x5 cube, 1 gap hiden 
004 Converging stairs 
005 Pyramid 9x9 base 
006 Perfect pyramid, my masterpiece, i think 
007 Another pyramid, and a cube 
008 Playing with holes 
009 Only 98 cubes 
010 Only 97 cubes 
011 These chessboard like are funny (and usually hard to arrange) 
012 A perfect one, 108 cubes, . 
013 There are many many geometrical combinations, symetrics are harder 
014 To get symetry, there is a hiden gap . 
015 Interlaced squares, one of multiple possibilities 
016 Another harmonic one 
017 Making it a bit more interesting (where to put the Zs pieces?) 
018 Mandalas are hard . 
019 Another mandala 
020 Isolated cubes are harder to arrange than in lines. 
This is one of the solutions 
Currently only 1 solution exist /SOMA004 ;Paulo 20100325 /............/............/............/............/.....LL..... /............/............/............/............/.....LZ..... /............/............/............/.....aZ...../.....LZ..... /............/............/.....tT...../.....aZ...../.....aa..... /............/.....tT...../.....tT...../.....TT...../.....BA..... /.....PP...../....vPpV..../...vvpPVV.../..ZZBppAZZ../LZZaBBAABZZL /.....Pp...../....Vppv..../...VVPPvv.../..aaApPbBB../LLLaAAbbBLLL /............/.....Tt...../.....Tt...../.....TT...../.....Ab..... /............/............/.....Tt...../.....BZ...../.....BB..... /............/............/............/.....BZ...../.....LZ..... /............/............/............/............/.....LZ..... /............/............/............/............/.....LL.....
